Answer:
The shadow length is 67
Step-by-step explanation:
solution shown in the picture
Given that,
The equations : 2f-5g=-9 and -7f+3g=4
To find,
The solution of the above equations.
Solution,
We have,
2f-5g=-9 ....(1)
-7f+3g=4 ......(2)
Multiply equation (1) by 7 and equation (2) by 2.
14f-35g=-63 ....(3)
-14f+6g=8 ......(4)
Add equation (3) and (4)
14f-35g -14f+6g = -63 + 8
-29g = -55
g = 55/29
g = 1.89
Put the value of g in equation (1).
2f-5(1.89)=-9
2f = -9+5(1.89)
f = 0.225
Hence, the solution of the above equations are g = 1.89 and f = 0.225.
Answer:
The cost of producing 60 t-shirts is $495.
36 t-shirts will let the cost, C(x) = 303
Step-by-step explanation:
If we producing 60 t-shirts, then we plug in 60 for the x, which x represents t-shirts for the marching band.
C(x) = 8x + 15
C(x) = 8(60) + 15
C(x) = 480 + 15
C(x) = 495
If the cost of the t-shirts is 303, we plug in 303 for the cost,C(x).
C(x) = 8x + 15
303 = 8x + 15
288 = 8x
x = 36
The temperature in Fahrenheit after preheating for 2 minutes is 103⁰F
The question looks incomplete but we can as well find the temperature in Fahrenheit after preheating for 2 minutes
Give the function t = 19m + 65 that represents the temperature t (in degrees Fahrenheit) of an oven after preheating for m minutes.
If t = 2,
t = 19(2) + 65
t = 38 + 65
t = 103⁰F
Hence the temperature in Fahrenheit after preheating for 2 minutes is 103⁰F
