Answer:
A.26
B. 3.4
Step-by-step explanation:
A. Using the Pythagorean theorem, we get x^2= 24^2+10^2. Solving for x, we get x=26.
B. Using the Pythagorean theorem again, we get x^2=3^2+1.6^2 solving for x, we get x=3.4
The answer is $295. I also added my work below!
Step-by-step explanation:
Given equations
2x + 5y = 6 .......i)
2x = 10 - 3y...... II)
Putting 2x = 10 - 3y in equation i
10 - 3y + 5y = 6
2y = 6 - 10
2y = - 4
y = - 4 / 2
y = - 2
Now putting y = - 2 in equation ii
2x = 10 - 3 * ( - 2)
2x = 10 + 6
2x = 16
x = 16 / 2
x = 8
So x = 8 and y = - 2

Answer:
A cookie costs 1 dollar. A brownie costs 2 dollars.
Step-by-step explanation:
C = Cookie B = Brownie
Your two equations:
3c + 2b =7
5c + 4b = 13
Make both equations have an equivalent section:
2(3c + 2b = 7)
6c + 4b = 14
5c + 4b = 13
c = 1
To find B's value:
3c + 2b = 7
3 x 1 + 2b = 7
3 + 2b = 7
2b =4
b =2
Hope this helps.
