Solve for c in the equation 32c = 128.

pishuonlain [190]

Answer

A. c = 4

Explanation

In algebra, what you do to one side of the equation, the same has to be done on the other side.

32c = 128

divide both sides by 32

32c = 128.

32c ÷ 32 = 128 ÷ 32

c = 128/32

= 4

a units 2 b units 2 c units 2

12 units 2 + (22.5)=c units 2

144+506.25=c units 2

650.25=c units 2

$\sqrt{x} 650.25$ =c units 2

Write at least 2 numerical expressions for each written phrase below. Then, solve.

zloy xaker [14]

Answer:

a. $\frac{3}{5}(7)\text{ or }\frac{3\times 7}{5}$

b. $\frac{1}{6}(4\times 8)\text{ or }\frac{4\times 8}{6}$

Step-by-step explanation:

In numerical expressions we write numbers with the mathematical symbols ( i.e. '+', '-' etc )

a. Given phrase,

Three fifths of seven,

$\frac{3}{5}(7)$

$=\frac{3\times 7}{5}$

$=\frac{21}{5}$

$=4\frac{1}{5}$

b. One sixth the product of four and eight,

$\frac{1}{6}(4\times 8)$

$=\frac{4\times 8}{6}$

$=\frac{32}{6}$

$=5\frac{1}{3}$

For a rotation of 90o: (x, y) ⇒ (–y, x)
T(3,4) ⇒⇒⇒ T'(-4,3)
W(-2,-1) ⇒⇒⇒ W'(1,-2)
x(-3,3) ⇒⇒⇒ x'(-3,-3)
