Answer:
8+2x/5=2
2x/5=2-8
2x/5=-6
2x=-6x5
2x=-30
x=-30/2
x=-15
Step-by-step explanation:
If 30% of a number is 15, what is 25% of the number?
Answer:
12.5
Step-by-step explanation:
Basically, the number was multiplied by .3 to get 15. So if you do 15/.3 you'll get your original number which is 50. Then you multiply by .25 and get 12.5.
(x+3)^2 = x^2-3(1-x)
Which of the following is most likely the next step in the series?
Answer:
its either A, or B
Step-by-step explanation:
hehehhe
Answer:
B
Step-by-step explanation:
The numbers in each of the circle halves are all in the blue side therefore all numbers on the red side would be eliminated. Leaving you with the options of B or C.
Now the Blue side for every pair is facing each other. So C would be eliminated because the red side is facing the start of the second pair ( A.K.A the third circle)
Leaving us with B.

Answer:
The true statements are;
A. The point (0, -3) is on the line
C. The point (-6, -6) is a point on the line
Step-by-step explanation:
The question relates to the finding of the equation of a straight line graph
The x-intercept of the graph is (6, 0) and the graph passes through the point (2, -2)
Therefore, the slope of the graph is m = (-2 - 0)/(2 - 6) = 0.5
The equation of the graph in point and slope form is given as follows;
y - 0 = 0.5 × (x - 6)
∴ y = 0.5·x - 3
Therefore, the equation of the graph in slope and intercept form, y = m·x + c is also y = 0.5·x - 3
A. The y-intercept of the graph is (0, -3), therefore, the point (0, -3) is on the line
B. The equation of the graph, y = 0.5·x - 3, can be written as follows;
8·y = 8 ×0.5·x - 8 × 3 = 4·x - 24
∴ 8·y - 4·x = -24
C. When y = -6, 'x' is given as follows;
y = 0.5·x - 3
-6 = 0.5·x - 3
0.5·x = -6 + 3 = -3
x = -3/0.5 = -6
x = -6
Therefore, when y = -6, x = -6, and (-6, -6) is a point on the line
D. When x = 0, 'y', is given as follows;
y = 0.5·x - 3
When x = 0, y = 0.5 × (0) - 3 = -3
Therefore the point (0, -3) is on the line and the point (0, -4) is not on the line
E. The point (-6, 0) represent an x-intercept of a line graph, however the x-intercept on the given line is (6, 0) and when y = 0 on the line, x = 6
Therefore, the point (-6, 0) is not on the line
F. The equation of the graph is 8·y - 4·x = -24, therefore, - 4·x + 8·y = 24 does not represent the equation of the graph
10 = - 1/4x +12
Answer pls
Answer: x = 8
Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
10= -1/4x+12
move the 12 to the other side
10-12= -1/4x
-2= -1/4x
divide -1/4 by both sides
8=x

x = 18
Step-by-step explanation:
use proportions. line up the sides based on the congruent angles. the sides opposite the singles line angle. = the sides opposite the double angle sides.

camila drew a triangle with a side that is 24 inches long and a side that is 18 inches long. which of the following could be the length of the third side of a triangle that camila drew?
please help thanksss
Answer:
40 seconds
Step-by-step explanation:
The answer is 40 because the y axis would be altitude and the x axis would be time. As altitude decreases time increases. When the line crosses the x axis then that is your answer shown above.

Suppose the band is raising money to help offset the cost of a trip. You
make $10 off of each box of oranges sold and $15 off of each box of
grapefruit sold. The band wants to raise at least $500.00. Write an
inequality to represent this situation.
Answer:
y-step explanation:
Answer:
10o + 15g ≥ 500
Step-by-step explanation:
Variables:
O = oranges
G = grapefruit
10 boxes of oranges (10o) and 15 boxes of grapefruit (15g) are being added together (10o + 15g). The band wants to raise AT LEAST (greater than or equal to ≥) $500.00.
Put that together, and it's:
10o + 15g ≥ 500

Is 1 3/23 a rational number
Answer:
Yes
Step-by-step explanation:
In mathematics rational means "ratio like." so a rational number is one that can be written as the ratio of two integers. 1 3/23 can be converted into 26/23, which is a ratio, therefore, 1 3/23 is a rational number.

If longest out of a triangle is 3 inches longer than the shorter side. The medium size is 2 inches longer than the shorter side. If the perimeter is 26 inches, what are the length of the three sides
Answer:
Shortest side = 7 inches.
Medium side = 9 inches.
Longest side = 10 inches.
Step-by-step explanation:
Let the shortest side be x.
Translating the word problem into an algebraic equation, we have;
Shortest side = x
Medium side = x + 2
Longest side = x + 3
The perimeter of a triangle is given by the addition of all its three (3) sides.
Mathematically, the perimeter of a triangle is given by the formula;
[tex] P = A + B + C [/tex]
Substituting into the equation, we have;
26 = x + x + 2 + x + 3
26 = 3x + 5
3x = 26 - 5
3x = 21
x = 21/3
x = 7 inches.
Therefore, the length of the three sides are;
Shortest side = x = 7 inches.
Medium side = x + 2 = 7 + 2 = 9 inches.
Longest side = x + 3 = 7 + 3 = 10 inches.
