Step-by-step explanation:
Simplifying
3x + -1s = r
Reorder the terms:
-1s + 3x = r
Solving
-1s + 3x = r
Solving for variable 's'.
Move all terms containing s to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-1s + 3x + -3x = r + -3x
Combine like terms: 3x + -3x = 0
-1s + 0 = r + -3x
-1s = r + -3x
Divide each side by '-1'.
s = -1r + 3x
Simplifying
s = -1r + 3x

Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Probability of rolling an even number P(A):
[tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Probability of flipping tails P(B):
[tex]\frac{1}{2}[/tex]
P(A OR B) = P(A) + P(B) – P(A AND B)
[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{2}[/tex] - ([tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]) = [tex]\frac{3}{4}[/tex]
Caleb throws a ball three times for his dog Leo. For each throw, Leo either
catches the ball or misses it. Identify the sample space (the correct list of
possible outcomes) for the results.
C = catch, M = miss
The notation CMC means Leo caught the first ball, missed the second one,
and caught the third one.
A. {CCCC, CCMM, MMMM}
B. {CCC, CCM, CMC, MCC, MMC, MCM, CMM, MMM}
C. {CCC, CMC, MMM}
D. {CC, CM, MC, MM}
Answer:
B {CCC, CCM, CMC, MCC, MMC, MCM, CMM, MMM}
Step-by-step explanation:
Ima try to explain this in the process of elimination:
A isn't right since he only throws the ball 3 times
C isn't right, since he could catch it, miss, then catch again and would still match the criteria stated.
D Isn't right since he threw it 3 times, not twice
that only leaved B to be correct! Hope this helps!
b. Write an equation that shows the relationship 64% of
y is 40.
c. 45 of x is 72 find the value if x
B.
[tex]0.65 \times y = 40 \\ y = \frac{40}{0.65} [/tex]
C.
[tex].45 \times x = 72 \\ x = \frac{72}{.45} \\ x = 160 \\ 45 \: percent \: of \: 160 \: is \: 72[/tex]

Answer:
y+1 = -1/3(x+3)
Step-by-step explanation:
we can use this formula to answer this question
y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the point and m indicates the slope
y-(-1) = -1/3(x-(-3)
y+1 = -1/3x-1
y = -1/3x -2

How many grams is in one decigram
Answer:
0.1
Step-by-step explanation:
1 Decigram (dg) is equal to 0.1 gram (g). To convert decigrams to grams, multiply the decigram value by 0.1 or divide by 10. For example, to convert 5 dg to g, multiply 5 by 0.1, that makes 0.5 g in 5 dg.
