I’m pretty sure the answer is (2,1)
2.964 bolts
Because 7.8*.38=2.964
I believe the answer to 1/7 times 20 would be 2.9 that is rounded to the nearest tenth but if your rounding to the nearest whole number it would be 3
As for 1/9 of 82 it would be 9.1 rounded to the nearest tenth and it would be 9 rounded to the nearest whole number.
Step-by-step explanation:
Hey there!!
Given,

Cross multiply.
15 = 2z
Therefore, z= 15/2

<span>d=420-65t. Geometric figure: Straight Line. Slope = -0.031/2.000 = -0.015; d-intercept = 420/1 = 420.00000; t-intercept = 420/65 = 84/13 = 6.46154. Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : d-(420-65*t)=0.</span>
