It's 10 - 4
moving decimal over to the right makes a negative exponent.
Answer:
the answer is 10 5. you welcome
For the entirety of this problem, p will represent a pair of pants and b will represent a bracelet.
Step 1) Set up equations for Destiny and Guadalupe
Destiny: 178 = 2p + 6b
Guadalupe: 155 = 3p + 2b
I will be using substitution to solve this problem, but elimination can also be used.
Step 2) Solve Destiny's equation for p
178 = 2p + 6b
178 - 6b = 2p
89 - 3b = p
Step 3) Substitute the found value of p from Destiny's equation into Guadalupe's equation and solve for b
155 = 3(89 - 3b) + 2b
155 = 267 - 9b + 2b
155 = 267 - 7b
-7b = -112
b = 16
Step 4) Use the value of b found in step 3, plug that back into our equation from step 2 and solve for p
89 - 3(16) = p
89 - 48 = p
p = 41
one pair of pants = $16
one bracelet = $41
Hope this helps!! :)
Answer:
1,120 yd²
Step-by-step explanation:
Surface area of triangular prism = 2(BA) + P*H
✔️Triangular base area (BA) = ½bh
b = 15 yd
h = 8 yd
Base area (BA) = ½*8*15 = 60 yd²
✔️Perimeter of the base (P) = 17 + 15 + 8 = 40 yd
✔️Height or lenghtbor prism (P) = 25 yd
✔️Surface area = 2(60) + 40*25 = 120 + 1,000 = 1,120 yd²
