Answer:
x=-96
Step-by-step explanation:
isolate x by moving -124x to the other side by adding -124x to -126x = -2x
then it will look like: 102= -2x-90
add 90 to both sides: 192= -2x
divide both sides by -2 to isolate x

Gary has 24 sweets. He eats 3/8 of them.
Ben has 30 sweets. He eats 2/5 of them. Who has the most sweets left?
no of sweet gave to peny is 24×3/8 = 9 sweets
rest was ate by him
so the sweet ate by him is 24-9 = 15 sweet
hope this helps you kindly mark me as brainliest and follow me
Based on the amount of sweets eaten by Gary and Ben, the person with more sweets left is Ben.
Who has more sweets left between Ben and Garry?The sweets left by Gary are:
= 24 - (24 x 3/8)
= 24 - 9
= 15 sweets
The sweet left by Ben are:
= 30 - (2/5 x 30)
= 30 - 12
= 18 sweets
In conclusion, Ben has more sweets left.

Identify the slope and y-intercept of each of the following lines. Then graph each line.
y = 5
Answer:
Below!
Step-by-step explanation:
Since the "y" variable is on the L.H.S, we can rewrite y = 5 in slope intercept form to determine the slope and the y-intercept.
⇒ y = 5⇒ y = 0x + 5Now, let's compare the equation of the line with the formula.
⇒ y = 0x + 5 and y = mx + bThus, we will obtain the following equations:
⇒ y = y⇒ m (Slope) = 0⇒ x = x⇒ b (Y-intercept) = 5============================
Thus, the slope is 0 and the y-intercept is 5. Since the slope is 0, the line will be a horizontal line that intersects the y-intercept.
In this case, the y-intercept is 5. Thus, the line will be a horizontal line, intersecting the y-intercept (5). (Refer to graph).
If we simplify
y=0x+5Hence..

Answer:
20 peopleStep-by-step explanation:
25% = 1/4 of 100
100 represents 200 people here, that means that if 25 = 1/4 to 100, then it is 1/8 to 200. 25x8=200
If 25% = 50, since 50x4=200 and 1/4 = 25% of 100%.
50... ok......
50 = 25%
Now, because there are 5 parts in 25, let's divide 5 by 50, that is 10. That means that 5 = 10 in that 50. 5% = 10 people
So, if 25-15=10
and then 5% = 10 people
5%+5%=10
10+10=20
That means, that 20 people more liked the movie than disliked it.

Which products result in a difference of squares? select three options. (x minus y)(y minus x) (6 minus y)(6 minus y) (3 x z)(negative 3 x z) (y squared minus x y)(y squared x y) (64 y squared x squared)(negative x squared 64 y squared)
The three (3) products that resulted in a difference of squares are:
(3 + xz)(-3 + xz) (y² - xy)(y² + xy)(64y² + x²)(-x² + 64y²)How to determine the difference of squares?In Mathematics, the standard form for a difference of two (2) squares is given by a² - b² = (a + b)(a - b).
(3 + xz)(-3 + xz) = (3 + xz)(xz -3)
(3 + xz)(xz -3) = 3xz - 9 + x²z² - 3xz.
(3 + xz)(xz -3) = x²z² - 9
Therefore, x²z² - 9 ≡ a² - b²
(y² - xy)(y² + xy) = y⁴ + xy³ - xy³ - x²y²
(y² - xy)(y² + xy) = y⁴ - x²y²
Therefore, y⁴ - x²y² ≡ a² - b².
(64y² + x²)(-x² + 64y²) = (64y² + x²)(64y² - x²)
(64y² + x²)(-x² + 64y²) = 4096y⁴- 64y²x² + 64y²x² - x⁴
(64y² + x²)(-x² + 64y²) = 4096y⁴ - x⁴
Therefore, 4096y⁴ - x⁴ ≡ a² - b².

One of the diagonals of a rhombus is 15 cm long. if the rhombus has an area of 60 cm², find the length of the other diagonal.
Answer:
8.5
Step-by-step explanation:
area of a rhomus = (1/2)(product of its diagonals)
let the other diagonal be a
(1/2)(15a) = 60
15a= 120
a = 8
So let's find the hypotenuse of one of the right-angled triangles formed by the intersection of its diagonals
base = 4, height = 7.5
if h is the hypotenuse,
h^2 = 4^2 + 7.5^2
h = 8.5

Solve for x . 8x-3 & 4x+3
8x-3+4x+3=180
?x+_=180
Answer:
x = 15
Step-by-step explanation:
the 2 angles are a linear pair and sum to 180° that is
8x - 3 + 4x + 3 = 180
12x = 180 ( divide both sides by 12 )
x = 15
The angles are supplementary angles. Then the value of the variable 'x' will be 15.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The angles are 8x - 3 and 4x + 3. And they are supplementary angles. Then the equation is given as,
8x - 3 + 4x + 3 = 180
Simplify the equation, then we have
8x - 3 + 4x + 3 = 180
12x + 0 = 180
x = 15
The angles are supplementary angles. Then the value of the variable 'x' will be 15.
