5x-7=13x+17
minus 5x
-7=8x+17
minus 17
-24=8x
divide 8
-3=x

-42
6(x-4) is -42
Answer:
2.35y = 4.70
4 = 10w
55x = 111
Step-by-step explanation:
Hi, the division property of equality states that if we divide both sides of an equation by a non-zero number, the equality remains. (Both sides remain equal).
So, the equations that we have to use the division property of equality to solve are:
Dividing both sides by 2.35:
2.35y /2.35= 4.70/2.35
y= 2
4/10=10w/10
0.4=w
55x/55 =111/55
x = 111/55
Let’s x for guitar and y for drum
u got 8x + 10y = 130 and x + y = 14
calculator x = 5, y= 9 so 5 guitars and 9 drums were rented
Answer:
False
Step-by-step explanation:
Given that a researcher testing the effects of two treatments for anxiety computed a 95% confidence interval for the difference between the mean of treatment 1 and the mean of treatment 2
Also that confidence interval includes zero.
When confidence interval includes zero, we need not reject the null hypothesis since null hypothesis claims that difference =0
When confidence interval includes 0 it confirms that there is no difference and hence null hypothesis should be accepted.
