The brake horsepower of an engine that’s being tested is coupled to a dynamometer that has a radius arm of 1.70 feet is letter D. 170.
Note: "total" is from adding the first and last columns (middle column should be provided because it is a rate which cannot be added).
Amount x Cost = Amount x Cost
Cranberry: q $6.30 $6.30q
Apple: <u> 4 </u> <u>$3.60</u> <u> $3.60(4) = $14.40</u>
Total: 4 + q $4.50 = $6.30q + $14.40
$4.50(4 + q) = $6.30q + $14.40
$18.00 + $4.50q = $6.30q + $14.40
$3.60 = $1.80q
2 = q
Since you didn't provide the equation options, hopefully you can use the solution to help you decide which option to choose.
- 39/25x(5x-1) or -1.56(5x-1)
Answer:
The cost for 1 chair is $2.75 and the cost for 1 table is $8.75
Step-by-step explanation:
Use the elimination method of linear equations to find your answer.
Our equations for this problem are:
3c+5t=52 and 9c+7t=86
1. Multiply the entire first equation by -3.
-3(3c+5t=52)
2. Simplify the equation from above:
-9c-15t=-156
3. Stack the two equations on top of each other and add/subtract:
-9c-15t=-156
9c+7t=86
4. You should be left with -8t=-70. Simplify this to find the value of t:
t=8.75
5. Plug the value of t into any of the original equations and solve for c.
3c+5(8.75)=52
6. Simplify the equation above:
3c+43.75=52
7. Subtract 43.75 from both sides of the equation:
3c=8.25
8. Divide both sides by 3 to get your c value:
c=2.75
