Answer:
no solution
Step-by-step explanation:
What you do is get x by itself.
4 (5х + 3) - 9x = 11х
20x + 12 - 9x = 11x
11x + 12 = 11x
-11x +11x = 0 which means
no solution
Answer:
The volume of the cube is 1/2 x 1/2 x 1/2 = 1/8
length x width x height = volume
1x2x2.5=5
2 1/2 = 2.5 because 1/2=0.5
to divide fractions multiply the reciprocal. The reciprocal is the fraction flipped over
5 / 1/8 = 5 x 8/1
5x8/1=40
40 cubes

Answer:
Our fourth number is 52.
Step-by-step explanation:
Let our first even number be <em>x</em>.
Then the second even number must be (<em>x</em> + 2), the third (<em>x</em> + 4), fourth (<em>x</em> + 6), and the fifth (<em>x </em>+ 8).
They sum to 250. Hence:
Solve for <em>x</em>. Combine like terms:
Subtract 20 from both sides:
And divide both sides by five. Hence:
Thus, our sequence is 46, 48, 50, 52, and 54.
Hence, our fourth number is 52.
Answer:
$740.00
Step-by-step explanation:
85% of x is 629
Translate into algebra. Use a decimal in place of the percent:
.85x = 629
Divide by .85
x = 740
This answer makes sense because the regular price should be a little higher than the sale price. If they are paying 85% they're only getting 15% off.
Check:
740×.85 = 629
