Answer:
23
Step-by-step explanation:
This equation can be derived from the question
let a represent the initial number Gus started with
{[(a x 8) - 12] / 4 } + 7 = 50
subtract 7 from both sides of the equation
[(a x 8) - 12] / 4 } = 43
Multiply both sides of the equation by 4
(a x 8) - 12] = 172
Add 12 to both sides
8a =184
Divide both sides by 8
a = 23.

The quotient of 9x³ - 21x² + 12x divided by 3x is 3x² - 7x + 4.
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given, A cubic polynomial 9x³ - 21x² + 12x and being divided by 3x.
So, (9x³ - 21x² + 12x)/(3x).
= 9x³/3x - 21x²/3x + 12x/3x.
= 3x² - 7x + 4.
So, The quotient when 9x³ - 21x² + 12x and being divided by 3x is
3x² - 7x + 4.

a= 29 and b = 4
O a= 61 and b = 16
O a= 4 and b = 58
none of these
Please please
Answer:
first option
Step-by-step explanation:
In a parallelogram consecutive angle are supplementary, sum to 180, so
2a + 122 = 180 ( subtract 122 from both sides )
2a = 58 ( divide both sides by 2 )
a = 29
---------------
In a parallelogram the opposite sides are congruent, then
b + 6 = 10 ( subtract 6 from both sides )
b = 4

Ron cycled 510km last week he was under the rain for the 25percent of his journey how far did he travel under the rain? A b c d answer rain
Answer: 127.5km
Step-by-step explanation:
We are informed that Ron cycled 510km last week and that he was under the rain for the 25percent of his journey.
The distance travelled did under the rain will be gotten by multiplying 25% by 510km. This will be:
= 25% × 510
= 0.25 × 510
= 127.5km
He was in the rain for 127.5km

Find the surface area of the cuboid.
Please give me an explanation! I really don’t understand and I will mark you as brainliest if you get it right and give an explanation!
Answer:
76cm
Step-by-step explanation:
To find the surface area of the cube you need to find the area of each side. To do this you will multiply 2×5, to find the front area of the cube, for the top of the cube you will multiply 5×4, and for the side of the cube you will multiply 2×4. once you get the answer you will multiply it by 2 since you have a 3 dimensional shape.
A line passes through the point (-6,9) and has a slope of -5/2 . Write an equation in point-slope form for this line.
Answer:
y-9=-5/2(x+6)
Step-by-step explanation:
y-y1=m(x-x1)
y-9=-5/2(x-(-6))
y-9=-5/2(x+6)
An equation in point-slope form for this line would be y-9=-5/2(x+6).
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
Which is the required equation of a line in a point-slope form.
Thus,
y-y1= m(x-x1)
A line passes through the point (-6,9) and has a slope of -5/2 So,
y-9=-5/2(x-(-6))
y-9=-5/2(x+6)
Hence, an equation in point-slope form for this line would be y-9=-5/2(x+6).

Find the size of angle x.
Give your answer correct to 1 decimal place.
Answer:
x ≈ 31.0°
Step-by-step explanation:
From the right triangle given in the picture,
By applying tangent rule,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{9}{15}[/tex]
x = [tex]\text{tan}^{-1}(\frac{9}{15} )[/tex]
x = [tex]\text{tan}^{-1}(0.6)[/tex]
x = 30.96
x ≈ 31.0°
Therefore, measure of angle x is 30.0°

Use the given numbers and operations to complete an equation.
Answer:
Give brainliest please! The answer is 53.2 mph
Step-by-step explanation:
Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.
1:40 p.m. is 13:40.
Thus, they traveled for
13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes
that is hours.
Use formula:
where
