A 6th grade class did a weekend fitness challenge.
Each student set a goal of 75 minutes of fitness.
Morgan exercised for 93 minutes.
What percent of the goal did she achieve?
Your answer is : (blank)%
Ans
Step-by-step explanation:
(2x+1)(x+5)
6x-4xy
16x^2-25
Step-by-step explanation:
i believe what you need help on is simplifying the equations. so let's start with the first one.
====================================================================
(2x+1)(x+5) original problem
(2x)(x)+(2x)(5)+(1)(x)+(1)(5) we can break this down into smaller pieces so we know what we're dealing with in this equation.
2x2+10x+x+5 if we break this down a little more and add some bracket numbers, this is what we get.
2x2+11x+5 this is the most simplified equation.
====================================================================
6x−4xy original problem.
unlike the last problem, we can easily just... 6x + (−4xy).
−4xy+6x this is the most simplified equation.
====================================================================
ok, the last one. phew!
unfortunately, 16x^2-25 is actually the simplest it can get. so, let's try factoring.
if we factored, we would get...
(4x+5)(4x−5)
===================================================================

Keith will run at most 26 miles this week. So far, he has run 14 miles. What are the possible numbers of additional miles he will run? Use t for the number of additional miles he will run. Write your answer as an inequality solved for t.
Answer:
[tex]t \leqslant 12[/tex]
Step-by-step explanation:
We know that Keith has ran 14 miles already, and he's aiming to reach no more than 26 miles, this week.
So we can put:
[tex]14 + t \leqslant 26[/tex]
Since, 14 is the number we know, t represents the number we have yet to find, and 26 is the product of this inequality. (We use the less-than-or-equal-to sign, because Keith is only aiming for 26 or less miles.)
Now we solve:
Subtract 14 on both sides to get
[tex]t \leqslant 12[/tex]
So t is less-than-or-equal-to 12, meaning Keith has 12 or less miles to run in order to reach 26 miles.
Hope this helps :)
Btw, please let me know if I'm somehow wrong.

Step-by-step explanation:
the serving size for a toddlers daily vitamin c is 3/4 cup of orange juice. if there are 2 1/4
cups of orange juice how many servings of vitamin c are there for a toddler
Answer:
Three servings
To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .
2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4
9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings

A textbook company sells teacher editions
and student editions in package deals.
Each package includes 3 teacher editions
for every 65 student editions. Which
combination could a school order?
A.
9 teacher to 260 student editions
B. 12 teacher to 325 student editions
12 teacher to 260 student editions
Answer:
C. 12 teacher editions and 260 student editions
Step-by-step explanation:
We can use division to solve this problem
65 ÷ 3 = 21.66... we can round this to 22 student ones we get 1 teacher copy.
A. 260 ÷ 9 = 28.99... we can round to 29 students ones we get 1 teacher copy so this one isn't correct.
B. 325 ÷ 12= 27.083... we can round to 27 students ones we get 1 teacher copy so this one isn't correct.
C. 260 ÷ 12 = 65 ÷ 3 = 21.66... we can round this to 22 student ones we get 1 teacher copy so this option is correct
C
Is the only correct option
Find what the x is.
45= 5/7x
Answer:
x = 63
Step-by-step explanation:
Step 1: Multiply both sides by 7/5.
[tex]45 *\frac{7}{5}=\frac{5}{7}x*\frac{7}{5}[/tex] [tex]63 = x[/tex]Step 2: Check if solution is correct.
[tex]45 = \frac{5}{7}(63)[/tex] [tex]45 = 5 * 9[/tex] [tex]45 = 45[/tex]Therefore, x = 63.
x = 63
Step-by-step explanation:45 = 5/7x
=> 9 = x/7
=> x = 63.

To work out 20 + 5(3) you would multiply 5 and 3 first and then add the 20 to get a value of 35. Can you start at 35 and reverse those two steps to get back to 3? Explain the two steps you would take to do that.
Answer:
35-25= 15/5= 3
Step-by-step explanation:
First you subtract 25 from 35 then you divide 15 by 3.
Answer:
20+ 5x 3
20+15
35
reverse
35-20=15
15/ 5=3
Step-by-step explanation:
the opposite of additon is subtraction
the opposite of multiplication is division

The length and width of a square is 9.5 inches (for both) what is the area and perimeter?
Answer:
90.25, 38
Step-by-step explanation:
The area is the two sides multiplied against each other, so 9.5*9.5
Since it's a square all of the sides are 9.5 inches, so just multiply 9.5 times 4 for the perimeter
5/8 + 11/12
Someone help me please and thank you.

Answer:
1 13/24
Step-by-step explanation:
First we need to find the LCD (lowest common Denominator) which will be 24. When we multiply 8 x 3 = 24 we will also multiply 5 by 3 which equals 15. So 5/8 = 15/24. Then we multiply 12 x 2 = 24, and again we also multiply the numerator by the same number which is 11 x 2 = 22. So 11/12 = 22/24.
Now that we have the LCD then we can add up the two. So 15/24 + 22/24 = 37/24. Now we need to simplify that to 1 13/24. Thank you.
