Expand each expression and combine like terms if possible
2/3 (x+ 18 - 2x)
Answers
Answer:
This is the expression expanded
Step-by-step explanation:
First, you collect like terms. This would make the expression 2/3 * (-x + 18)
Then, remove the brackets, making the expression and the final answer -2/3x + 12

One-fourth(80)
Answers
Answer:
1/4(90)
Step-by-step explanation:
The most reasonable way to estimate 26% of 88 is one-fourth of 90. Therefore, the correct option is C.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, 26% of 88.
Now, 26/100 ×88
= 0.26×88
= 22.88
A) 1/5 ×90
= 18
B) 1/5 ×80
= 16
C) 1/4 ×90
= 22.5
D) 1/4 ×80
= 20
Therefore, option C is the correct answer.

Step-by-step explanation:
First inequality
7x -6 > 8
7x > 14 . . . . . . add 6
x > 2 . . . . . . . .divide by 7
Second inequality
3x+4 ≥ 22
3x ≥ 18 . . . . . . subtract 4
x ≥ 6 . . . . . . . . divide by 3
The values of x that will satisfy both inequalities are x ≥ 6. (All of those values are > 2.)
The solution to the inequalities is x ≥ 6.

A class has 30 boys and 20 girls. The average age of
boys is 11 yrs and girls 12 What is the
average age of the whole class."
Answers
x = total age of boys
x / 30 = 11yrs
Multiply both sides by 30
x = 330
y = total age of girls
y / 20 = 12
Multiply both sides by 20
y = 240
(240 + 330) / 50 = 11.4 yrs
The average age of the whole class = 11.4 years.
A class has 30 boys and 20 girls.
The average age of boys and girls is 11 and 12 respectively.
To Find:The average age of the whole class.
Solution:Boys = No. of boys × Age
Boys = 30 × 11 = 330
Girls = No. of girls × Age
Girls = 20 × 12 = 240
Average Age = Boys + Girls / Total no. of boys and girls
Average Age = 330 + 240 / 50
Average Age = 570 / 50
Average Age = 11.4
Answer:Average age of of the whole class is 11.4 .

Which are perfect square trinomials? Select two options. x2 − 9 x2 −100 x2 − 4x + 4 x2 + 10x + 25 x2 + 15x + 36
PLS HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
C and D
Step-by-step explanation:
i just took the quiz
From the given options, only x² - 4x +4 and x² +10x +25 are perfect square trinomials. The correct options are the third and forth options - x² - 4x +4 and x² +10x +25
Determining perfect square trinomialsRecal that,
An expression is a perfect square trinomial if it takes the form ax² + bx + c and satisfies the condition b² = 4ac
For x² -9a = 1, b = 0, c = -9
0² ≠ 4(1)(-9)
0 ≠ -36
∴ x² - 9 is NOT a perfect square trinomial
For x² - 100a = 1, b = 0, c = -100
0² ≠ 4(1)(-100)
0 ≠ -400
∴ x² - 100 is NOT a perfect square trinomial
For x² -4x +4a = 1, b = -4, c = 4
(-4)² = 4(1)(4)
16 = 16
∴ x² - 4x +4 is a perfect square trinomial
For x² +10x +25a = 1, b = 10, c = 25
(10)² = 4(1)(25)
100 = 100
∴ x² +10x +25 is a perfect square trinomial
For x² +15x +36a = 1, b = 15, c = 36
(15)² ≠ 4(1)(36)
225 ≠ 144
∴ x² - 4x +4 is a NOT perfect square trinomial
Hence, from the given options, only x² - 4x +4 and x² +10x +25 are perfect square trinomials. The correct options are the third and forth options - x² - 4x +4 and x² +10x +25
