Answer:
answer is x=3 and y=5.... so it is (3,5)
Step-by-step explanation:
you want to combine them so y=3x-4 so subsitute y
-2x+5(3x-4)=19
-2x+15x-20=19
+20 +20
13x=39
--- ---
13 13
x=3
now subsitute 3 into x into any problem...
3(3)-4=y
9-4=y
and 9-4 is 5 so it is...

The two prisms below are similar. What is the value of x?
24
4
16
A. 4
B. 24
C. 16
D. 1
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.

The measure of an exterior angle of a triangle is 40°. What is the sum of the measures of the corresponding remote interior angles?
Answer:
Remember that the two non-adjacent interior angles, which are opposite the exterior angle are sometimes referred to as remote interior angles. An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 degrees
One number is 2 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 468 , find the numbers
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

There is no "b" in this y = mx + b, so it has to go through zero, eliminating the bottom two. If we insert y = 2(1), the point should be at (1, 2), and if when looking at the possible answers, we can go with letter H.
Dennis can walk about 2 5/6 miles each hour. About how far can he walk in 3 hours 15 minutes?
Answer:
24 13/34
Step-by-step explanation:
The distance covered by Dennis will be 9.23 miles.
What is speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is a scalar quantity and does not require any direction to represent it.
Given that Dennis can walk about 2(5/6) miles each hour. The distance covered by Dennis in 3 hours 15 minutes will be calculated as:-
Distance = 2 ( 5 / 6) x 3 hour 15 minute
Distance = 2.84 x 3 ( 1 / 4)
Distance = 2.84 x 3.25
Distance = 9.23 miles.
Therefore, the distance covered by Dennis will be 9.23 miles.

$430.88.
yo
Q: Find Jeff's total earnings if his sales are$948.
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:
Ill be delighted to help
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°
