19^2 or 361 is the answer to the equation
I’ve broken it down into the parts that you’ve highlighted:
Part A:
x = 25 + y
x + y = 95
Part B:
I’m using the substitution method to find the amount of time that Eric plays volleyball, so:
x + y = 95
x = 95 - y
95 - y = 25 + y
70 = 2y
y = 35, 35 minutes spent playing volleyball
Part C: i don’t completely understand the question, perhaps there was a typo?
Answer:
the answer is -4
Step-by-step explanation:
Answer:
a. 180 - 90 + 65
180 - 155 = 25 degrees
b. 5^2 + 6^2 = 61
61
: 7^2 = 49 close enough 8^2 = 64 too much. 7 is your answer.
c. 100 divided by 0.10 = 1000
Answer:
Step-by-step explanation:
Your answer
Assume that
Sammie is x,,,, Jennie is 9 years younger than him. So, Jennie ( y) = x-9
According to second condition eq is
(X-5) = 4(y-5)
Place the value of y in eq 2
You will find x= 17
Put x in eq 1
Y = 8
