A. 4
B. 24
C. 16
D. 1
Answers
Answer:
A
Step-by-step explanation:
Since the prisms are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{16}{4}[/tex] = [tex]\frac{x}{1}[/tex] ( cross- multiply )
4x = 16 ( divide both sides by 4 )
x = 4 → A
The value of x on the prism is 4.
What are Similar Figures?Similar figures are those figures which are having the same shape, but the sizes are different.
Given are two prisms.
We have to find the length of x.
Given that they are similar.
So the ratio between their dimensions is equal.
So,
x / 1 = 16 / 4
x = 4
Hence the value of x is 4.

8° + 6x is an exterior angle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
In this situation, those two angles are 30° and 4x+2°
So lets put this in an equation
30° + 4x + 2° = 8° + 6x
4x + 32° = 6x + °8
Now lets subtract 8° from both sides to make it simpler
New equation =
4x + 24° = 6x
Lets evaluate X=
6x - 4x = 24°
2x = 24°
x= 24/2
x= 12°

Jeff's weekly salary equals a commission of his

earns $417.92. If his sales are $1011, he earns
$430.88.
yo
Q: Find Jeff's total earnings if his sales are$948.
Answers
Answer:
His total earnings for sales of $948 is $425.84
Step-by-step explanation:
Let the percentage of his commission be a percentage with its value represented as x and b be his base salary , y as his total earnings
So we have;
y = x% of sales + base salary
for 849 sales and 417.92 , we have
417.92 = 8.49x + b •••••••(i)
for 1011 sales and 430.88 servings
430.88 = 10.11x + b ••••••(ii)
Subtract i from ii
12.96 = 1.62x
x = 12.96/1.62
x = 8
To get b, we substitute
430.88 = 10.11(8) + b
b = 430.88 - 10.11(8) = 350
Commission is 8% , base earnings is $350
So for total sales of 948;
y = 8% of 948 + 350
y = $425.84

Step-by-step explanation:
They're vertical angles, so they are equal:
5x + 4 = 49
subtract 4 from both sidese
5x = 45
divide both sides by 5
x = 9
Answer: x=9
Step-by-step explanation: First of all, the two shown inner angles are equivalent. This allows you to set up an equation like: (5x+4)=49
Then simply use algebra to solve...
(5x+4)=49
-4 -4 (subtract "4" from each side)
5x=45
5x/5=45/5 (divide each term in the equation by "5")
x=9

Answers
Answer:
Step-by-step explanation:
Givens
Let the first number = x
Let the second number = 2x
Let the third number = x + 100
Total = 468
==============
Solution
x + 2x + x + 100 = 468 Combine the xs
4x + 100 = 468 Subtract 100 from both sides
4x = 468 - 100
4x = 368 Divide by 4
x = 368/4
x = 92
===============
Answer
First number = 92
Second num = 2 * 92= 184
Third number = 92 + 100= 192
Total 468
Which table matches 4x+7y=19?
Answers
Answer:
c
Step-by-step explanation:
The table which matches 4x + 7y = 19 is table (d).
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Given is a linear equation,
4x + 7y = 19
(a) When x = -18,
7y = 19 - (4 × -18) = 91 ⇒ y = 13
When x = 1,
7y = 15 ⇒ y = 2.14
So the table (a) is not the one.
(b) When x = -9, 7y = 55, y = 7.857
Table (b) is also not the one.
(c) When x = 0, y = 2.7
Hence (c) is also not an option.
(d) When x = -18, y = 13
When x = -11, 7y = 63, y = 9
When x = -4, 7y = 35, y = 5
So the correct option is table (d).
Hence the correct option is table (d).
