Answer:
x = 9
Step-by-step explanation:
Step 1: Write equation
4(x - 2) = 3x + 1
Step 2: Solve for <em>x</em>
- <u>Distribute 4:</u> 4x - 8 = 3x + 1
- <u>Subtract 3x on both sides:</u> x - 8 = 1
- <u>Add 8 to both sides:</u> x = 9
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
- <u>Substitute:</u> 4(9 - 2) = 3(9) + 1
- <u>Parenthesis (add):</u> 4(7) = 3(9) + 1
- <u>Multiply:</u> 28 = 27 + 1
- <u>Add:</u> 28 = 28
Both expressions are related because 12 divided by 4 equals to 3, and 1/4 of 12 equals to 3 too.
Answer:
A princess is stuck at the top of a tower that is 20 ft tall. To get down she shoots an arrow with rope attached into the ground and it lands 15 ft away from the tower. how long is the rope to safely guide her onto the ground.
Step-by-step explanation:
using the Pythagorean theory which is a squared plus b squared equals c squared you will see that 20 squared plus 15 squared will equal 625. Once you have that answer you find the square root of 625 which will give you your overall answer of 25.
Answer:
d=104
Dasha's garden had 104 originally
Step-by-step explanation:
let d for dasha and a for Anna
d=4a
a=d/4
d-39=a+39
d-39=d/4 +39
d-d/4=39+39
3/4 d =78
3d=4*78
d=(4*78)/3
d=312/3
d=104
