1ST Piece =======> 2x ======> 2 * 3 ft. ======> 6 ft.
2ND =========> 5x =======> 5 * 3 ft. ======> 15 ft.
3RD ==========> 4 Feet =======> 4 ft.
Sum ======> 25 Feet
Equation:
(2x + 5x) + (4) = 25
Let's solve your equation step-by-step.
2x + 5x + 4 = 25
Step 1: Simplify both sides of the equation.
2x + 5x + 4 = 25
(2x + 5x) + (4) = 25 (Combine Like Terms)
7x + 4 = 25
7x + 4 = 25
Step 2: Subtract 4 from both sides.
7x + 4 − 4 = 25 − 4
7x = 21
Step 3: Divide both sides by 7.
7x / 7 = 21 / 7
Answer ========> x = 3
Check:
(2x + 5x) + (4) = 25
2(3) = 6
5(3) = 15
3rd Piece = 4
Sum = 25
6ft. + 15ft. + 4ft = 25
25 = 25
Hope that helps!!!!!!!!!!!!! : )
Hello!
To find this ordered pair, we solve for x and y and put them together in an ordered pair.
-4+y=8
x-5y=17
Let's solve the first equation for y.
y= 12
Now, let's plug 12 into the second equation for y.
x-5(12)=17
x-60=17
x=77
Therefore, our ordered pair is (77,12)
I hope this helps!
Your answer is 75, hope this helps you!
Answer:
7/10 or 0.7
Step-by-step explanation:
cross multiply to get 40x+20=48
subtract 20 from both sides to get 40x=28
divide both sides by 40 to get 7/10
HOPE THIS HELPS!!!:)
Answer:
54 liters
Step-by-step explanation:
the right term to describe the capacity is volume
volume = height × length × width
(depth and height have the same meaning)
volume = 30 × 30 × 60
volume = 54000 cm³
1 liter = 1 dm³
54000 cm³ = 54000÷ 1000
(why divided by 1000 not 10? because its cm³ which means cm × cm × cm => 10 × 10 × 10)
54000 cm³ = 54 dm³
then
54 dm³ = 54 liters
