Solve for X
Answer:
x = 44
Step-by-step explanation:
These angles are supplementary so that means they add up to 180:
47 + 3x + 1 = 180
3x + 48 = 180
3x = 180 - 48
3x = 132
x = 44

Write an equation to model the statement the product of – 8 and (y + 3) is 32.
How you can use the equation to reason about the value of y?
PLS HELP! I WILL GIVE BRANLY
Answer:
-8*(y+3)=32
Step-by-step explanation:
y+3=32/-8
y=32/-8 -3
y = -7
The equation to model the statement is -8(y + 3) = 32 and the value of y is -7.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given statement is the product of – 8 and (y + 3) is 32.
Product means the operation is multiplication.
So the equation can be written as,
-8 (y + 3) = 32
Dividing both sides by 8,
-(y + 3) = 4
y + 3 = -4
y = -4 - 3 = -7
Hence the value of y is -7.

Samantha leaves her house and drives 18 kilometers east to her friend's house. She then drives north to school. Finally, she drives 30 kilometers directly home, in a straight line, from school. A map of Samantha's route is provided below.
How far does Samantha drive traveling from her friend's house to the school?
A.
42 kilometers
B.
12 kilometers
C.
35 kilometers
D.
24 kilometers
Answer:
the answer is D) 35
Step-by-step explanation:
use the formula b²×h²
The distance travelled by Samantha from her friend's home to school will be 24 KM
What is pythagoraean theorem?The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the square of the other two sides.
Here Samantha is travelling in a right-angled triangular path so the distance between Samantha's school and her friend's home will be calculated as:-
H² = P²+B²
(30)² = x²+(18)²
x²= 900-324=576
x=√576
x=24 KM
Hence the distance travelled by Samantha from her friend's home to school will be 24 KM

Can someone please help me find the measure of the exterior angle.
Answer:
X=128°
Step-by-step explanation:
Because an exterior angle of a triangle is equal to of the two opposite interior angle.
The sum of the exterior and interior angle is equal to 180°
In this case the part marked red = 90° because is a right angled triangle.
90+38=128
180- 128=52
180- 52=128
x=128.
Answer:
128 degrees.
Step-by-step explanation:
Simply add 38 degrees with 90 degrees.
(the square in the corner means 90 degrees)
If a number becomes 2.5 times smaller, by what percent was it decreased?
Answer: 40%
Step-by-step explanation: 1 Divided by 2.5 is 0.4, or 40%.
The number decreased by 150%
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here a number becomes 2.5 times smaller than let the number be x then the value of the number the decrease is = x - 2.5x
= -1.5x
Thus the percentage decrease is = -1.5x/x × 100
= - 150%
Hence, The number decreased by 150%

What is 4x + 10 = -26
Answer:
x = -9
Step-by-step explanation:
I'm assuming you're looking for X.
So first, you'll want to subtract 10 from both sides of the equation.
4x + 10 = -26
- 10 | -10
4x = -36
Then from there, you'll want to divide by 4. This allows us to get x by itself.
4x = -36
/4 | /4
x = -9
The value of 'x' is -9 in the given equation.
To solve the equation 4x + 10 = -26, follow these steps:
Step 1: Isolate the variable term by subtracting 10 from both sides of the equation.
4x + 10 - 10 = -26 - 10
4x = -36
Step 2: Solve for 'x' by dividing both sides of the equation by 4.
4x / 4 = -36 / 4
x = -9
So, the value of 'x' is -9.
