What is the value of x that makes the given equation true? -90 = -100 + x
A. -10
B. 10
C. -190
D. 190
-90 = -100+x
-90+100=X
+10 =X
OPTION B:- 10
Option B :- 10
Explanation :
[tex] - 90 = - 100 + x \\ - x = - 100 + 90 \\ - x = - 10 \\ x = 10 \\ [/tex]
Lena used a total of 3 5/6 gallons of gas while driving her car. Each hour she was driving, she used 7/9 gallons of gas. What was the total number of hours she was driving?
Step-by-step explanation:
3 x 5/6 = 2.5 gallons of gas used
7/9 galllons per 1 hour
Hence if she used 2.5 gallons,
2.5 ÷ 7/9 =
[tex]3 \frac{3}{14} hours[/tex]
Jack's family took a road trip to Mount Rushmore. Jack slept through the last 65% of the trip. If the total length of the trip was 700 miles, how many miles had they travelled when Jack fell asleep?
Using proportions, it is found that they had traveled 245 miles when Jack fell asleep.
What is a proportion?A proportion is a fraction of a total amount.
Jack slept through the last 65% of the trip, hence he fell asleep when 100 - 65 = 35% of the 700 mile trip had been traveled, so:
0.35 x 700 = 245.
They had traveled 245 miles when Jack fell asleep.

Find the area of the trapezoid
Answer:
49 units squared
Step-by-step explanation:
The area of a trapezoid is calculated with the following formula:
(a+b)*1/2*h (a: base, b: base, h: height)
(3+11) * 1/2 * 7 = 49 the area is stated in square units so the answer is 49^2

Solve each equation by factoring
3x^2-14x=-8
3x² - 14x + 8 = 0
Δ = (-14)² - 4*3*8 = 196 - 96 = 100 = 10²
2 solutions
x' = (14 + 10) / (2*3) = 24 : 6 = 4
x" = (14 - 10) / (2*3) =4/6 = 2/3
3 (x - 4) (x - 2/3) = 0
A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be the other equation?
O 2y = 16x +14
O y = 8x - 7
O y = -8x + 7
O 2y = -16x - 14
Answer: y=8x-7 just took the quiz hope that helps
The other equation could be y = 8x - 7
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
here, we have,
to determine the other equation:
The first equation is given as:
y = 8x + 7
For the system of equation to have no solution, then the equations in the system would have different constant values.
Take for instance:
y = 8x + b
Where:
b is a constant not equal to 7
From the options, we have:
y = 8x - 7
Notice that -7 and 7 are not the same
Hence, the other equation could be y = 8x - 7

What is the equation of the line that contains the point (-1 , 4) and has a slope of 3?
Step-by-step explanation:
Let's write the equation with formula:- Where, x1 is -1 and y1 is 4 and m is 3Thus, The correct choice is option C.
Step-by-step explanation:
Equation of line formula=> y=mx+c
Let take point (-1,4) as (x, y) and slope m=3
4= 3(-1) +c
4= -3+c
4+3=c
7=c
Therefore by using equation of line formula we get
y= mx+c [m=3 , c=7]
y=3x+7

The developmental department for a National Lawn Care Services Provider is interested in improving products and services. The germination periods, in days, for grass seed are normally distributed with a population standard deviation of 7 days and an unknown population mean. If a random sample of 17 types of grass seed is taken and results in a sample mean of 37 days, find the error bound (EBM) of the confidence interval with a 98% confidence level.
Answer:
3.949
Step-by-step explanation:
We can use the formula to find the error bound:
EBM=(zα/2)(σn/√)
We know that σ=7 and n=17. We are also given that the confidence level (CL) is 98%, or 0.98. So, we can calculate alpha (α).
α=1−CL
=1−0.98
=0.02
Since α=0.02, we know that
α2=0.022=0.01
The value of z0.01 is 2.326. Now we can substitute the values into the formula to find the error bound.
EBM=(zα/2)(σ/√n)
=(2.326)(7/√17)
≈(2.326)(1.698)
≈3.949
So, the error bound (EBM) is 3.949.

Answer:
34.5 square meters
Step-by-step explanation:
We assume you want to find the area of the shaded region. (The actual question is not visible here.)
The area of the triangle (including the rectangle) is given by the formula ...
A = 1/2bh
The figure shows the base of the triangle is 11 m, and the height is 1+5+3 = 9 m. So, the triangle area is ...
A = (1/2)(11 m)(9 m) = 49.5 m^2
The rectangle area is the product of its length and width:
A = LW
The figure shows the rectangle is 5 m high and 3 m wide, so its area is ...
A = (5 m)(3 m) = 15 m^2
The shaded area is the difference between the triangle area and the rectangle area:
shaded area = 49.5 m^2 - 15 m^2 = 34.5 m^2
The shaded region has an area of 34.5 square meters.
