Answer:
140 coins total
Step-by-step explanation:
Straightforward, this reads "7 is 5% of how many?". Algebraically, the word "is" means an equals sign, and the word "of" means you multiply. Of course, the 5% needs to be in decimal form. Taking the sentence above, algebraically it is: 7 = .05x. Divide by .05 on both sides to get x = 140
Answer: D B
Step-by-step explanation:
<em>Step 1: Subtract x from both sides. </em>
1/3x +4− x =x −2− x
= -2/3 x +4 = -2
<em>Step 2: Subtract 4 from both sides</em>.
-2/3x + 4− 4 =−2− 4
-2/3x = -6
<em>Step 3: Multiply both sides by 3/(-2).</em>
( 3/-2 ) * (-2/3x ) = (3/-2) * (-6)
= 9
So , X=9
