which equation has the solution x = 3 ?
5x+ 4 = 22
6x + 1 = -19
3x - 2 = 34
6x + 6 = 24
Answer: D
Step-by-step explanation:
To see whuch equation has solution x=3. we can just plug x=3 into each equation to see which is correct. Let's actually solve each equation for practice.
A. Incorrect
5x+4=22 [subtract both sides by 4]
5x=18 [divide both sides by 5]
x=18/5
------------------------------------------------------------------------------------------------
B. Incorrect
6x+1=-19 [subtract both sides by 1]
6x=-20 [divide both sides by 6]
x=-20/6
------------------------------------------------------------------------------------------------
C. Incorrect
3x-2=34 [add both sides by 2]
3x=36 [divide both sides by 3]
x=12
------------------------------------------------------------------------------------------------
D. Correct
6x+6=24 [subtract both sides by 6]
6x=18 [divide both sides by 6]
x=3
Now, we know that D is correct.

3(d-8) - 5 = 9(d+2) + 1
Answer:
d = - 8
Step-by-step explanation:
3(d-8) - 5 = 9(d+2) + 1
3d-24 - 5 = 9d+18 + 1
3d - 29 = 9d + 19
9d - 3d = -29 - 19
6d = - 48
6d / 6 = -48/6
d = -8

Answer:
Step-by-step explanation:
∠ABD = 100
∠ABC + ∠CBD = ∠ABD
4x + 2 + 3x - 7 = 100
4x + 3x +2 -7 = 100 {Combine like terms}
7x -5 = 100
Add 5 to both sides
7x = 100 +5
7x = 105
Divide both sides by 7
x = 105/7
x = 15
∠CBD = 3x - 7
= 3*15 - 7
= 45 - 7
∠CBD = 48
Answer:
m∠CBD = 38°
Step-by-step explanation:
∠ABC and ∠CBD have a sum of 100°.
m∠ABC + m∠CBD = m∠ABD
4x + 2 + 3x - 7 = 100
7x - 5 = 100
7x = 105
x = 15
m∠CBD = 3(15) - 7 = 45 - 7 = 38
write an equation that contains points (0, 4) and is perpendicular to x-3y=-12
Answer:
y= -3x+4
Step-by-step explanation:
x+12=3y
(x+12)/3 = y
slope =
[tex] \frac{1}{3} [/tex]
the new slope = -3
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b
4 = -3×(0) + b
b= 4
so y= -3x+4

Step-by-step explanation:
The 5-year inflation rate between January 2009 and January 2014 is 10.78%.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Now, For calculate the 5-year inflation rate between January 2009 and January 2014, we can use the following formula:
Inflation rate = (CPI at end of period - CPI at beginning of period) / CPI at beginning of period x 100%
Hence, Using the values given, we can plug them into the formula:
Inflation rate = (233.916 - 211.143) / 211.143 x 100% Inflation rate
= 10.78%
Therefore, the 5-year inflation rate between January 2009 and January 2014 is 10.78%.
