Ok glad that you got an answer
A complete load of concrete = 8 parts gravel + 7 parts water + 5 parts cement.
Total number of parts in every load = 8 + 7 + 5 = 20 parts
If total load = 220 kg, then 20 parts = 220 kg
Divide each side by 20 : 1 part = 11 kg
gravel = 8 parts = 8 x 11 kg = <em>88 kg</em>
water = 7 parts = 7 x 11 kg = <em>77 kg</em>
cement = 5 parts = 5 x 11 kg = <em>55 kg</em>
<u>Check:</u> 88 + 77 + 55 = 220 yay !
Answer:
Step 1: Simplify both sides of the equation.
−2−3a=−23
−2+−3a=−23
−3a−2=−23
Step 2: Add 2 to both sides.
−3a−2+2=−23+2
−3a=−21
Step 3: Divide both sides by -3.
−3a−3=−21−3
<u><em>a=7</em></u>
Do 46.50 divided by 3. That gives you 15.5. Now do 15.5 multiplied by 4 because it says he deposited 3/4 of his paycheck.
The answer is 62.
(Sorry if there were any mistakes or if i read the question wrong) <span />
the 2 angles are congruent so...
x+40=3x set the 2 equations equal to each other
40=2x subtract x from both sides
20=x divide by 2
x=20 is the final answer
Have a blessed day!
