Answer:
x = 6
Step-by-step explanation:
Alternate angles are congruent.
7x - 9 = 3x + 15 {Subtract 3x form both sides}
7x - 3x -9 = 15
4x - 9=15 {Add 9 to both sides}
4x = 15+9
4x = 24
x = 24/4
x = 6

Step-by-step explanation:
Solve the simultaneous equations
2x + 4y = 22
2x + 2y = 15
Answer:
1. x= 11+-27
2.x = 7.5 + -1y
Step-by-step explanation:
1. Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
2x + 4y + -4y = 22 + -4y
Combine like terms: 4y + -4y = 0
2x + 0 = 22 + -4y
2x = 22 + -4y
Divide each side by '2'.
x = 11 + -2y
Simplifying
x = 11 + -2y
2.Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
2x + 2y + -2y = 15 + -2y
Combine like terms: 2y + -2y = 0
2x + 0 = 15 + -2y
2x = 15 + -2y
Divide each side by '2'.
x = 7.5 + -1y
Simplifying
x = 7.5 + -1y

C 17. At high school A, the mean score of 50 students on a science test is 75.
At high school B, the mean score of 40 students on the same test is 80.
What is the mean score of the 90 students?
Answer:
Mean score of 90 students = 77.2
Step-by-step explanation:
Mean score of 50 students from school A = 75
Mean score of 40 students from school B = 80
We need to find mean score of the 90 students?
First we will find sum of scores of students from school A
We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]
We have Average = 75, Number of terms = 50, We need to find Sum of terms (scores)
[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\75=\frac{Sum\:of\:Terms}{50}\\Sum\:of\:Terms= 75\times 50\\Sum\:of\:Terms=3750[/tex]
So, Sum of scores for School A = 3750
Now, we will find sum of scores of students from school B
We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]
We have Average = 80, Number of terms = 40, We need to find Sum of terms (scores)
[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\80=\frac{Sum\:of\:Terms}{40}\\Sum\:of\:Terms= 80\times 40\\Sum\:of\:Terms=3200[/tex]
So, Sum of scores for School B = 3200
Now, We will find mean score of the 90 students?
Mean score of 90 students will be:
[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\Average=\frac{3750+3200}{90}\\Average=\frac{6950}{90}\\Average = 77.2[/tex]
So, mean score of 90 students = 77.2
What is the percentage of sugar in the syrup made of 10 kg of water and 2 kg of sugar. Thx yall :D
Find m∠RSQ
please and ty
Answer:
m∠RSQ = 19°
Step-by-step explanation:
From the picture attached,
RT is the diameter of the a circle.
Angle subtended at the circumference by the diameter of a circle = 90°
Therefore, m∠RST = 90°
Since, m∠RSQ + m∠QST = m∠RST
m∠RSQ + 71° = 90°
m∠RSQ = 90° - 71°
= 19°
Therefore, measure of angle RSQ is 19°.

b. 32
Step-by-step explanation:
a. 12 + 4y
They gave us the value of "y" which is "5", and substitute that into the expression.
12 + 4y
12 + 4(5)
12 + 20
32
b. 4 (y + 3)
They gave us the value of "y" which is "5", and substitute that into the expression.
4 ( y + 3 )
4 ( 5 + 3)
Distributive property (multiply what is in the parenthesis by what is out of it (4))
4 * 5 + 4 * 3

1) The bakers at Healthy Bakery can make 290 bagels in 10 hours. How many
bagels can they bake in 23 hours? What was that rate per hour?
Answer:
667 bagels in 23 hours
29 bagels per hour
Step-by-step explanation:
We first find the unit rate in bagels per hour.
(290 bagels) / (10 hours) = 29 bagels/hour
Now we find the number of bagels made in 23 hours.
23 hours * 29 bagels/hour = 667 bagels

Solve 3(x + 2) >x
Please
Answer:
x > −3
Step-by-step explanation:
Let's solve your inequality step-by-step.
3(x + 2) > x
Step 1: Simplify both sides of the inequality.
3x + 6 > x
Step 2: Subtract x from both sides.
3x + 6 − x > x − x
2x + 6 > 0
Step 3: Subtract 6 from both sides.
2x + 6 − 6 > 0 − 6
2x > −6
Step 4: Divide both sides by 2.
2x / 2 > −6 / 2
x > −3
Answer:
x > −3
