Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is [tex]a^2 + b^2 = c^2[/tex]
a = 12
b = 16
and c would be x.
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20
$1500 at 9% for 2 years
Answer:$270
Step-by-step explanation:
I=PRT
Interest=principal times rate times time
Principal=1500
Rate=9%=0.09
Time=2
I=1500 times 0.09 times 2
I=1500 times 0.18
I=270
Interest=270
Total is 1500+270=1770 total paid
Find the value of each variable listed.
Answer:
a = 90
b = 28
c = 68
d = 22
Step-by-step explanation:
[tex]a = 90[/tex]
[tex]d=22[/tex]
[tex]22+90=112[/tex]
[tex]180-112=68[/tex]
[tex]c=68[/tex]
[tex]62+90=152[/tex]
[tex]180-152=28[/tex]

Complete the missing value in the solution to the equation:
6x + x = y + 2x
(3,
Answer:
-2
Step-by-step explanation:
Solve for y y + 7 = 9
Answer:
y = 2
Step-by-step explanation:
Given
y + 7 = 9 ( subtract 7 from both sides )
y = 2
Simplifying
y + 7 = 9
Reorder the terms:
7 + y = 9
Solving
7 + y = 9
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + y = 9 + -7
Combine like terms: 7 + -7 = 0
0 + y = 9 + -7
y = 9 + -7
Combine like terms: 9 + -7 = 2
y = 2
Simplifying
y = 2

what is the coefficient of -2x+8=10
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+8=10
Step 1: Subtract 8 from both sides.
−2x+8−8=10−8
−2x=2
Step 2: Divide both sides by -2.
−2x−2=2−2
x=−1
Answer:
Answer:
-2
Step-by-step explanation:
The coefficient of an equation or expression is any constant that precedes a variable. So, in this case, the only variable is x, so the coefficient is the preceding number, -2.
Zoe paid 18.60 in sales tax and tips for dinner. The sales tax is 11% and she tipped 20%. What was the price of Zoe’s dinner before sales tax and tip?
Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
Sales tax = 11% * original price = 0.11 * x= 0.11xTips for dinner = 20% * original price = 0.20 * x = 0.2x0.11x + 0.2x = 18.600.31x = 18.60x = 60$60 was the price of Zoe's dinner, before sales tax and tip.Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
1. Sales tax = 11% times original price = 0.11 times x= 0.11x
2. Tips for dinner = 20% times original price = 0.20 times x = 0.2x
3. 0.11x + 0.2x = 18.60
4. 0.31x = 18.60
5. x = 60
6. $60 was the price of Zoe's dinner, before everything else

Answer:
a) 13%
b) 65.9%
Step-by-step explanation:
a) You can use n=1 to find the percentage remaining at the end of 1 hour:
P = 100(0.87^1) = 87
This is 13% less than 100%, so the decay rate per hour is 13%.
__
b) Fill in n=3 and evaluate the expression.
P = 100(0.87^3) = 65.8503
After 3 hours, about 65.9% of the caffeine remains.

Liz lives 3 miles from the library.
Brendan lives 3 times as far as Liz.
Andy lives 3 times as far as Brendan.
Eddie lives 3 times as far as Andy.Which exponential expression represents how far Eddie lives from the library?
A.3 the the 5th power miles
B.4 to the 3rd power miles
C.3 to the 4th power miles
D.3 to the 3rd power miles
Answer:
C.
Step-by-step explanation:
3 times 3 =9 and is 3 by the 2nd power. Then that times three is 27 which is 3 to the third power. Now it’s time to find out where Eddie is compared to the library. Then that times 3 is 3 to the fourth power. So that’s how far Eddie is. He is 81 miles away.

Solve 4x + 8y = 16 for x.
O A. x=-8y + 4
O B. x= -2y+ 16
O C. x= -2y+ 4
D. X = 8y + 16
4x + 8y = 16
4x = 16 - 8y
4x = 4 (4 - 2y)
x = 4( 4 - 2y)/4
X = 4 - 2y
X = -2y + 4

the equation is 7x-3 over 9 > 8-2x
Answer:
solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]
First we will solve the inequality to find value of x
Solving:
[tex]\frac{7x-3}{9}\geq 8-2x[/tex]
Step 1: Multiply both sides by 9
[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]
Step 2: Adding 3 on both sides
[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]
Step 3: Add 18x on both sides
[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]
Step 4: Divide both sides by 25
[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]
So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.

If you solve the inequalty 2x < 14, the solution set is x < 7. Graph x < 7 on a number line. Which one of the listed values of x is included in x < 7
A) x=8
B) x = 7
C) x = 12
D) x= -8
Answer:
D) x = -8
Step-by-step explanation:
All the values less than 7 are included in the number line. The graph on number line is shown in figure attached. In the options given, all values in Option A, B and C are greater than 7 so these cannot be included.
