Answer:
x = 112
Step-by-step explanation:
We can create two equations 1. one that calculates calories burned and 2.another that calculates minutes:
20*x + 5*y = 1200
x + y = 120
Then we can solve for x
x = 120 - y
then we can plug that into the top equation:
20(120 - y) + 5y = 1200
divide by 5:
4(120 - y) + y = 240
distribute:
480 - 4y + y = 240
and then do all that combining like factors what not and simplify and solve:
480 - 3y = 240
-3y = -240
y = 8
NOW WE CAN JUST PLUG IN THE ANSWER FOR Y TO FIND X
8+x =120
x = 112
We know that:
Area= length*width
Plug in the stuff you know.
35= length(tall)*5
Divide both sides by 5.
7= length
The photo is 7 inches tall.
I hope this helps!

Step-by-step explanation:
s1 = 3
s2 = 3×2 = 6
s3 = 6×2 = 12
s4 = 12×2 = 24
s5 = 24×2 = 48
sn = sn-1 × 2 = s1 × 2^(n-1)
s17 = 3 × 2¹⁶ = 3 × 65,536 = 196,608
Answer:
Step-by-step explanation:
Given:
19x + 9y = 15
Required:
Rewrite in slope-intercept form, y = mx + b
SOLUTION:
19x + 9y = 15
Subtract 19x from both sides
9y = -19x + 15
Divide both sides by 9
y = -19x/9 + 15/9
