Find the value of x.

Mathematics
1 answer:
Anna [14]3 years ago
6 0

Answer:

x = 5.

Step-by-step explanation:

ZY = 2*2x = 4x.   (Parallel line in a triangle theorem).

XZ = 2 * (4x + 1) = 8x + 2

XY = 2 *(2x + 3) = 4x + 6

So the perimeter 88 = 4x + 8x + 2 + 4x + 6

88 - 8 = 16x

16x = 80

x = 5.

(Sorry but I can't remember the exact name of the theorem).

If you deposit $6000 into an account paying 8% annual interest compounded monthly, how much money will be in the account after 7
Leviafan [203]

Answer:

$10278

Step-by-step explanation:

Given data

P= $6000

R= 8%

T= 7 years

The compound interest formula is

A=P(1+r)^t

substitute

A=6000(1+0.08)^7

A=6000(1.08)^7

A=6000*1.713

A=$10278

290 is 10 times as much as?
katrin2010 [14]
I'm pretty sure it's 29 . . . A way to remember is that when you multiply a number by ten, add a zero. For example, 34 x 10 is 340. Just add the zero!

I need someone to solve this
LUCKY_DIMON [66]

Answer:

?? = 900

Step-by-step explanation:

Solve algebraically

let x be ball and y be cube

x + y = 100

x - y = 80

xy = ??

We can solve by elimination. Eliminate one of the variables by adding OR subtracting the entire equations. I will add.

.     x + y = 100

<u>+    x - y = 80</u>       y + - y = y - y = 0; The variable is eliminated

.        2x = 180      Divide both sides by 2 to isolate x

.          x = 90

Substitute x = 90 into one of the equations.

x + y = 100

90 + y = 100  Isolate y by subtracting 90 from both sides

y = 100 - 90

y = 10

Find xy = ?? by substituting y for 10 and x for 90.

xy = (90)(10) = 900

Therefore the value of ?? is 900.
