X + 7x = 56 + 8

Simplifying x + 7x = 56 + 8 Combine like terms: x + 7x = 8x 8x = 56 + 8 Combine like terms: 56 + 8 = 64 8x = 64 Solving 8x = 64 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Divide each side by '8'. x = 8 Simplifying x = 8

Use A as the subject of formula<br>p= A ( 1+r\100)

ZanzabumX [31]

Answer:

$A = \frac{100 P}{100+r}$

Step-by-step explanation:

Given $P = A( 1 + \frac{r}{100} )$

To make A as the subject of the formula we need to rearrange

Divide by $(1 +\frac{r}{100})$ throughout we get

$\frac{P}{1+\frac{r}{100}} = A$

$A = \frac{100P}{100 + r}$

given triangle UVW is congruent to triangle TSR find the values of x (12x-7), y (5y-33), and z (3z+14)

timama [110]

Answer:

Step-by-step explanation:

Find the image attached. For two triangles to be congruent, then the sides of UVW is equal to that of TSR

From the diagram given

TR = UW

Given

TR = 50

UW = 3z+14

Equate and find z;

3z+14 = 50

3z = 50-14

3z = 36

z = 36/3

z = 12

VW = RS

Given

VW = 27

RS = 5y - 33

Equate

5y-33 = 27

5y = 27+33

5y = 60

y = 60/5

y = 12

Also TS = UV

TS = 53

UV = 12x+7

Equate:

12x-7 = 53

12x = 53+7

12x = 60

x = 60/12

x = 5

Hence x = 5, y = 12 and z = 12

Find the percent of change round to the nearest percent original 32.5 new:30

tatuchka [14]

Percent change = ((new value) - (old value))/(old value) × 100%
= (30 - 32.5)/32.5 × 100%
≈ -8%
