Here are some
1 ) 4 ( x - 3 )
2 ) 10 x - 2 x - 12
3 ) 8 x - 4 - 8
Answer:
Step-by-step explanation:
Let us call the width of the rectangle "x." Since the length of the rectangle is five less than twice its width," we can express the length of the rectangle as 2x - 5 (since 2x = twice the width and - 5 indicates "five less").
***
Now, using x as the width and 2x - 5 as the length, we can create an equation. We know that the perimeter is 86 feet, and the perimeter of a rectangle is the same thing as adding up its sides together: length + length + width + width, or 2*length + 2*width. Thus, we can create the equation
2(length) + 2(width) = 86
Substituting in our expressions for width and length, we get
2(2x - 5) + 2(x) = 86
Now we can just solve for x
2(2x - 5) + 2x = 86
Distribute: 4x - 10 + 2x = 86
Add like terms: 6x - 10 = 86
Add 10 to both sides: 6x = 96
Divide both sides by 6: x = 16

I hope these help</h2>
If the number of adult tickets are taken as x then the number of children’s tickets can be taken as (89 — x ) then we can set up the equation
4.10(x) + 2.70 (89 — x) = 331.30
4.10x + 240.3 — 2.70x = 331.30
1.4x = 331.30 — 240.30
1.4x = 91
X = 65
Therefore 65 adult tickets and 24 children tickets as 89 — 65 is 24
Y=4x-3 ? The graph us kind of hard to see but I think that's the answer
Answer:
The student must get at least 86 in the next text in order to get an upper A average.
Step-by-step explanation:
The scores in the three tests are: 91, 94 and 89
The average score here is = 91 (rounded off to nearest whole number)
In order to get an Upper A average after tackling the next test, the students total score in the four tests must be 90 × 4 = 360
Let's say the student scores x in the fourth test.
Then; 91 + 94 + 89 + x ≥ 360
274 + x ≥ 360
x ≥ 360 - 274
x ≥ 86
