Alyssa starts with $30 and saves $5 each week. Bill has $16 and saves $7 each
week. At what week will Alyssa and Bill have the same amount of money?
Answer:
7 weeks
Step-by-step explanation:
Given data
Alyssa starts with $30 and saves $5 each week
let the number of weeks be x
y= 30+5x----------1
Bill has $16 and saves $7 each
week.
y= 16+7x----------------2
equate 1 and 2
30+5x= 16+7x
30-16= 7x-5x
14= 2x
x= 14/2
x= 7 weeks
Ann and bill shared £440 in the ratio 9:2 Ann gives bill some of her money Bill now has the same amount as ann
Answer:
Bill gave Ann £220
Step-by-step explanation:
plz mark brainliest :D
Ann shared £360 and Bill shared £80.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Ann and bill shared £440
Ratio = 9:2
Total is = 9+ 2= 11
So, Anna shred
= 9/11 x 440
= 360
and Bill shred
= 2/11 x 440
= 80

It took the football team 5 h to travel from Titletown, a total distance of 1320 km. Part of the trip was by bus and the remainder by plane. The bus averaged 40 km/h and the plane 600 km/h. How many hours were spent travelling by bus?
Answer:
It took 2 hours by plane
Step-by-step explanation:
let bus is represented by x and plane is represented by y
the total distance of bus and plane will be represented by equation:
40 x + 600 y = 1320 (1)
the total time taken by bus and plane will be represented by:
x + y = 5 (2)
solving equations (1) and (2) simultaneously:
Multiply by 40 on both sides in eq (2) and then subtract (1) and (2)
40 x + 600 y = 1320
40 x + 40 y = 200
_______________
560 y = 1120
y = 1120/ 56
y= 2
since plane is represented by y so, the time they spent travelling by plane is 2 hours.

Answer: m∠5 = 75°.
Step-by-step explanation:
We know that lines A and B are parallel, and angles 1 and 5 are formed by the same line intersecting the parallel lines.
We know that:
"When a line intersects two parallel lines, corresponding angles are formed, such that we could think on four quadrants, the angles in each quadrant are equivalent between them"
Well, here we can see that angle ∠1 and angle ∠5 are formed by the same line, and both are in the same quadrant (would be the third quadrant if we use standard notation)
Then the measure of ∠1 is the same as the measure of ∠5
And we know that m∠1 = 75°
Then we must have that m∠5 = 75°.
Solve the inequality 3(x - 2) > 15
Answer:
x > 7
Step-by-step explanation:
i dont know if this is right but i think so
The solution is x > 7
The value of x from the inequality equation 3 ( x - 2 ) > 15 is x > 7
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
3 ( x - 2 ) > 15 be equation (1)
On simplifying the equation , we get
3x - 3 ( 2 ) > 15
3x - 6 > 15
Adding 6 on both sides of the inequality equation , we get
3x > 21
Divide by 3 on both sides of the inequality equation , we get
x > 21/3
x > 7
Therefore , the value of x is greater than 7
Hence , the inequality equation is x > 7

Barry is 66 inches tall which best represents Barry's height in centimeters
Answer:
Barry is 167.64 inches
Step-by-step explanation:
The best represents Barry's height in centimeters is: 167.64cm
Here, we have,
given that,
Barry is 66 inches tall.
we know that,
1 inch is approximately 2.54 centimeters
Since 1 foot = 2.54 centimeters
all we need to do is to multiply 66 with 2.54
i.e. 66 × 2.54 = 167.64
The answer will be 84.
best represents Barry's height in centimeters is: 167.64cm.

Find the area of this shape? HELP Radius is 2 area is 3.14
Answer:
Step-by-step explanation
what I learned was to separate the two shapes.
So the rectangle and the triangle will be multiplied separately.
We will make the 10 an 8 because of the 2 on top of the rectangle.
5*8= 40 because the shape is a triangle we divide the area of it by 2, and that would make 20. The triangles area is 20.
Now the rectangle: 2*3=6
Add both of those numbers and the answer is 26 ft.

Two more than 11 times a number is equal to 24. What is the number?
Answer:
2
Step-by-step explanation:
Brainliest?!?!?!?
The answer to this would be 2.
Step by Step Explanation
Equation: 11x+2=24
Variable for the missing number: x
To do this, I suggest writing out an equation with the variable X to represent the missing number that we are trying to find. The equation would look something like this: 11x+2=24.
From here, to solve the equation, subtract 2 from both sides, which would then get the equation to be 11x=22. From here, you would then divide both sides by 11 to get the variable on it's own, which would be x=2. Since x is the variable that we are using to represent the missing number, the missing number would be 2.

Answer:
Part A: B
Part B: 1
Step-by-step explanation:
Part A:
The meaning of "at most" is "less than or equal to." If we assume that the variables x and y represent numbers of loaves of banana bread and nut bread, respectively, then the first problem statement tells you ...
x + y ≤ 30 . . . . . the total of loaves baked is at most 30
Only one answer choice has this inequality listed: choice B.
__
Part B:
The numbers of loaves of bread will not be negative. The only quadrant that has both coordinates positive is the 1st quadrant.
__
Comment on quadrant
Real-world problems involving numbers of items are often expressed in terms similar to those seen here. The assumption that is made in all such problems is that the quantity of items cannot be negative. That is, the constraints x ≥ 0 and y ≥ 0 are always considered part of the problem description. These limit solutions to Quadrant 1. (or I, if you use Roman numerals for numbering quadrants)
