Step-by-step explanation:
(7x+3) (10x-14)
70[tex]x^{2}[/tex]-98+30x-42
70[tex]x^{2}[/tex]+30x-42-98
70[tex]x^{2}[/tex]+30x-140
Answer:
x = 9
Step-by-step explanation:
These are vertical angles, and thus the angles are equal.
7x + 3 = 10x - 24
Combining like terms, we get
27 = 3x, so that x must be 9.
x = 9

What is the measure of LXZW?
850
150°
Y
65°
95
Z
215°
W
30°
Answer:
so the answer is 95°
Step-by-step explanation:
The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°. Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.

This means he can read 45 pages in 1 hour.
The unit rate is 45 pages in 1 hour.
Tom swam at one pool each of 5 days during one week. The number of people at the pool when he arrived on each of the days were: 12, 19, 17, 26, 26. What is the mean number of people who were at the pool?
Answer:
The mean is 19.33
Step-by-step explanation:
How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
A box in the shape of a triangular prism is painted for a project. Which formula would be used to find the lateral surface area of the triangular prism?
Answer:
LSA = (a+b+c)×h
Step-by-step explanation:
The formula that would be used to find the lateral surface area of the triangular prism = perimeter of base(P) × Height of prism(H)
Let us assume that three side of triangle are a, b, c and height of prism is h
Then lateral surface area of the prism can be LSA = (a+b+c)×h
0/1 Solve the equation by completing the square. Round your answer to the nearest hundredth, if necessary x^2+18x=7
Answer:
The solution to the equation is x = 0.38 or -18.38
Step-by-step explanation:
x^2+18x=7 can be properly written as
[tex]x^{2} +18x =7[/tex]
To solve by completing the square, divide the coefficient of x by 2, square and then add to both sides
i.e 18/2 = 9
Then add 9² to both sides of the equation
[tex]x^{2} +18x + 9^{2} = 7 + 9^{2}[/tex]
This becomes
[tex](x+9)^{2} = 7 + 81[/tex]
[tex](x+9)^{2} = 88[/tex]
[tex]x+9 = \pm \sqrt{88}[/tex]
[tex]x = -9 \pm\sqrt{88}[/tex]
[tex]x = -9 \pm 9.38[/tex]
∴ [tex]x = -9+9.38 or -9-9.38[/tex]
[tex]x = 0.38 or -18.38[/tex]
Hence, x = 0.38 or -18.38

Tiffany scored 80 on the exam.
Find the Z-score for Tiffany's exam grade. Round to two decimal places.
Answer:
0.85
Step-by-step explanation:
The Z-score for Tiffany's exam grade will be 0.85. The value of Z score for the different distribution is different.
What is the z score?The z-score is a numerical assessment of a value's connection to the mean of a set of values, expressed in terms of standards from the mean, that is used in statistics.
The Z score is found as;
[tex]\rm Z= \frac{x-\mu}{\sigma} \\\\ Z=\frac{80-77}{3.5} \\\\ Z=0.85[/tex]
Hence,the Z-score for Tiffany's exam grade will be 0.85.
