Solve the equation for x:
| 4x - 3] = 7
Answer:
x=-1, 5/2.
Step-by-step explanation:
abs(4x-3)=7
4x-3=7, 4x-3=-7
4x=7+3=10
x=10/4=5/2
----------------
4x=-7+3
4x=-4
x=-4/4=-1
Answer:
x = 2.5 or 5/2
Step-by-step explanation:
4x - 3 = 7
+3 +3
4x = 10
divide by 4
x = 2.5, or 5/2

John lays tile for a living. While trying to create the perfect design for his client, he then drew this pattern containing two right angles and an isosceles triangle.
For the triangles to fit together perfectly, John must determine the measure of angles 1, 2, and 3.
Answer:
Angle 1= 58
Angle 2= 64
Angle 3= 58
Step-by-step explanation:
The two smaller triangles are each right triangles and every triangle equals 180 so add 32 degrees and 90 degrees ( 90+32=122) and subtract that from 180 and you get angles 1 and 3 from your isosceles triangle
then you add both angles 1 and 3 from your isosceles triangle which are 58 degrees each (58+58=116) and subtract that from 180 (180-116=64) and you get angle 2
Answer:
angle 1 = 32
angle 2 = 116
angle 3 = 32

The line of best fit for a data set is y=1.1x+3.4. Find the residual for each of the coordinate pairs, (x,y).
D. (1.5,5.05)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the model:
y=1.1x+3.4
Find the residual:
Residual = Yactual - y
A. (5, 8.8) ; Yactual = 8.8
Residual = 8.8 - (1.1(5) + 3.4) = - 0.1
B.) (2.5,9.95) Yactual = 9.95
Residual = 9.95 - (1.1(2.5) + 3.4) = 3.8
C.) (0, 3.72) Yactual = 3.72
Residual = 3.72 - (1.1(0) + 3.4) = 0.32
D.) (1.5,5.05) Yactual =
Residual = 5.05 - (1.1(1.5) + 3.4) = 0
What is the measure of all exterior angles of a pentagon
Answer:
72 degrees for each exterior angle and 360 degrees for all of them summed.
Step-by-step explanation:
An exterior angle of a polygon is the angle between the line extending one of its sides and the next side. As you go around a regular n sided polygon doing this, you will rotate through a complete circle of 360 degrees. All these angles are equal, so each one is 360/n.
For the pentagon, n=5, so the sum of all its exterior angles is 360 degrees and each exterior angle is 360/5=72 degrees.

200% of d is 11 what is D
If 200 percent is 11 then 100 is 11/2 which is exactly 5.5.
Answer:
5.5
Step-by-step explanation:
200 percent * 5.5 =
(200 divided by 100) * 5.5 =
(200 * 5.5) divided by 100 =
1100 divided by 100 = 11

Joseph has $80 in his bank account and spends $32 each day.
Joseph has $80 in his bank account and earns $32 each day.
Joseph had $32 in his bank account and deposited another $80.
Joseph has $32 in his bank account and earns $80 each day.
Question 5(Multiple Choice Worth 4 points)
(05.05)David and Amanda are trying to figure out how long they can live off their $12,350 savings if they spend $240 each month. They have each created an equation.
David’s Equation Amanda’s Equation
y = 12,350 – (240x) y = 12,350 + (240x)
Which person has the correct equation to model this linear relationship?
Amanda’s equation is correct, because their spending will be multiplied by the number of months and then added to their savings.
Amanda’s equation is incorrect, because their spending will increase the amount of their savings.
David’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.
David’s equation is incorrect, because their spending should be a fixed amount and should not be multiplied.

Amrita is 8 years elder to her brother Aman. If the ratio of their ages is 7 : 3, find their present ages?
Answer:
Amrita = 14 years old
Aman = 6 years old
Step-by-step explanation:
Find out the difference of the units.
7 - 3 = 4
Amrita is 4 units/8 years older than Aman.
4 units = 8
1 unit = 8 ÷ 4 = 2
Amrita is 7 units and her brother is 3 units.
Amrita = 7 units x 2 = 14
Aman = 3 units x 2 = 6

Answer:
103 ft^2
Step-by-step explanation:
Long sides: 2(8*4) = 64 ft^2
Under side: 3*8 = 24 ft^2
Triangles: (2(3*5))/2 = 15 ft^2
64+24+15 = 103
Answer:
103
Step-by-step explanation:
the base = 3x8 = 24
the sides are= 4 x 8 = 32
two sides = 64
triangle = 5x 3 x1/2 = 7.5
7.5 x 2 = 15
total = 103
