Answer:
x = -5
Step-by-step explanation:
-3 - 3x = -4( 2x + 7 )
Distributive property
-4 * 2x - 4 * 7
-3 - 3x = -8x - 28
Add 3 on both sides
-3 + 3 - 3x = -8x - 28 + 3
-3x = -8x - 25
Add 8x on both sides
-3x + 8x = -8x + 8x - 25
5x = -25
Divide by 5 on both sides to isolate the variable
5x/5 = -25/5
x = -5

Answer:
x = -5
Step-by-step explanation:
Rearrange terms
-3−3=−4(2+7)
−3−3=−4(2+7)
Distribute
−3−3=−4(2+7)
−3-3=−8−28
Add 3 to both sides of the equation
−3−3=−8−28
−3−3+3=−8−28+3
Simplify
Add the numbers:
−3−3+3=−8−28+3
−3=−8−28+3
Add the numbers:
−3=−8−28+3
−3=−8−25
Add 8 to both sides of the equation
−3=−8−25
−3+8=−8−25+8
Simplify
Combine like terms
−3+8=−8−25+8
5=−8−25+8
Combine like terms
5=−8−25+8
5=−25
Divide both sides of the equation by the same term
5=−25
5x/5 = -25/5
Simplify
Cancel terms that are in both the numerator and denominator
5x/5 = --25/5
x= -25/5
Divide the numbers
x= -25/5
x = -5

Solve for x.
8(x-1)=-4x+136
Step-by-step explanation:
Given
8(x - 1) = - 4x + 136
8x - 8 = -4x + 136
8x + 4x = 136 + 8
12x = 144
x = 144 / 12
x = 12

1/2 + 3/8 = 4+3/8 = 7/8
Answer:
7 / 8
Step-by-step explanation:
In order to add fractions, the denominators must be the same.
1 / 2 + 3 / 8
Find the least common denominator by prime factorization.
2:2
8:2, 2, 2
To determine the least common denominator (LCD), multiply the common factor 2 times the other factors in blue.
LCD = 2 × 2 × 2 = 8
Multiply 1 / 2 times 4 / 4 so that it will have a denominator of 8.
1 / 2 × 4 / 4 + 3 / 8
= 4 / 8 + 3 / 8
= 7 / 8

2. Which variable will eliminate? *
3x +6y=27
-3x+8y= 1
Answer:
the x variable
Step-by-step explanation:
Given the 2 equations
3x + 6y = 27 → (1)
- 3x + 8y = 1 → (2)
Since the signs of the coefficients of x are opposite, then adding them will eliminate the x- term, that is
Add (1) and (2) term by term
0 + 14y = 28
14y = 28 ( divide both sides by 14 )
y = 2
Then substitute y = 2 into either equation for corresponding value of x

Triangles MNQ and MOP are similar. What is the slope of segment MO?
A. 1/3
B. 1/2
C. 2/3
D. 3/2
Answer:
D. 3/2
Step-by-step explanation:
The scale factor is 1/2 from OP / NQ = 1/2. Because of that, MQ is equal to half of MP and QP is equal to half of MP. Therefore, QP = MQ = 2. The slope of MO is rise over run which is 6 / 4 or 3 / 2.

Answer:
x = 2
z = 85°
Step-by-step explanation:
95° + z = 180°
z = 180 - 95
z = 85°
z + (11x + 73) = 180°
85 + (11x + 73) = 180°
11x + 85 + 73 = 180°
11x + 158 = 180°
11x = 180 - 158
11x = 22
x = 22/11
x = 2
HELP ME PLZ>>>>>THANKYOU
Answer:
(4, 6 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 36 → (1)
y = - [tex]\frac{1}{2}[/tex] x + 8 → (2)
Substitute y = - [tex]\frac{1}{2}[/tex] x + 8 into (2)
3x + 4(- [tex]\frac{1}{2}[/tex] x + 8) = 36 ← distribute and simplify left side
3x - 2x + 32 = 36
x + 32 = 36 ( subtract 32 from both sides )
x = 4
Substitute x = 4 into (2) for corresponding value of y
y = - [tex]\frac{1}{2}[/tex] × 4 + 8 = - 2 + 8 = 6
solution is (4, 6 )
If Tim plotted the points 2,4 and 6,4 What is the equation of a line that passes both of tim’s points ?
Answer:
y = 4
Step-by-step explanation:
1. Find the slope
slope = rise over run or change in y divided by change in x
The slope of (2,4) and (6,4) is
(4 - 4)/(6 - 2) = 0/4 = 0
the slope is 0
2. Use point-slope form: y - y₁ = m(x - x₁)
(2, 4) -> x = 2 y = 4
m -> (slope) = 0
y - 4 = 0(x - 2)
y - 4 = 0
y = 4
¿Cuáles son las longitudes de un terreno rectangular, si se sabe que el ancho es dos veces más pequeño que el largo, y que su área es de 16, 200 m2? cuanto mide el ancho cuanto mide el largo
Answer:
El largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m
Step-by-step explanation:
Un rectángulo es un cuadrilátero con dos lados de igual longitud y dos lados de igual ancho que contiene cuatro ángulos rectos. Para encontrar el área de un rectángulo, debes multiplicar su longitud por su ancho. Es decir, el área del rectángulo es igual al largo por el ancho.
En este caso, sabes que el ancho es dos veces más pequeño que el largo. Entonces, siendo el largo x, el ancho tendrá un valor de x÷2.
Siendo el área del terreno rectangular 16,200 m², entonces
x*(x÷2)= 16,200 m²
Resolviendo:
x² ÷2= 16,200 m²
x²= 16,200*2 m²
x²= 32,400 m²
x= √32.400 m²
x= 180 m
Entonces, el largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m (180 m÷ 2)

Find the value of each variable in the parallelogram?
Answer:
Step-by-step explanation:
In parallelogram opposite angles are equal
6x = 66 {Divide both sides by 6}
x = 66/6
x = 11
20y - 46 = 13y + 10 {Add 46 to both sides}
20y - 46 + 46 = 13y + 10 + 46
20y = 13y + 56 {Subtract 13y from both sides}
20y - 13y = 13y-13y + 56
7y = 56 {Divide both sides by 7}
y = 56/7
y = 8
A quantity with an initial value of 990 grows exponentially at a rate such that the quantity doubles every 4 years. What is the value of the quantity after 0.7 decades, to the nearest hundredth?
Answer:3329.95
Step-by-step explanation:
The value of the quantity after 0.7 decades, to the nearest hundredth is 1157.37.
Given that, a quantity with an initial value of 990 grows exponentially at a rate such that the quantity doubles every 4 years.
What is the exponential function?Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
We know that, S.I=(P×T×R)/100
Amount after 4 years is 1980
So, 990= (990×4×R)/100
⇒ 39.6R=990
⇒ R=990/39.6
⇒ R=25%
Amount = [tex]a(1+r)^t[/tex]
= [tex]990(1+0.25)^{0.7}[/tex]
= 1157.37
Therefore, the value of the quantity after 0.7 decades, to the nearest hundredth is 1157.37.
