Answer:
1. 11
2. 20
3. 34
4. 12.6
5. 18
6. 105
Step-by-step explanation:
We are told that ---> t = 0, x = 1.5, y = 6, and z = 23
1. y + 5
= 6 + 5
= 11
2. z - 2x
= 23 - 2(1.5)
= 23 - 3
= 20
3. 2z - 2y
= 2(23) - 2(6)
= 46 - 12
= 34
4. 2.6y - 2x
= 2.6(6) - 2(1.5)
= 15.6 - 3
= 12.6
5. 4(y - x)
= 4(6 - 1.5)
= 24 - 6
= 18
6. 4(2 + z) + 5
= 4(2 + 23) + 5
= 8 + 92 + 5
= 105

[tex]\large \mathfrak{Solution : }[/tex]
let's solve for x :
first step : adding 7 on both sides
[tex]9x - 7 = 10[/tex][tex]9x - 7 + 7 = 10 + 7[/tex][tex]9x = 17[/tex]next step : dividing by 9 on both sides :
[tex] \dfrac{9x}{9} = \dfrac{17}{9} [/tex][tex]x = \dfrac{17}{9} [/tex]now, let's check for the solution by Plugging the value of x as 17 / 9 in the above equation.
[tex]9x - 7 = 10[/tex][tex](9 \times \dfrac{17}{9} ) - 7 = 10[/tex][tex]17 - 7 = 10[/tex][tex]10 = 10[/tex]we can see that the LHS = RHS, therefore our value for x is correct. i.e 17 / 9

If a + b = 20 and ab = 75, find the value of a + b?
Answer:
a=5 or a=15, b=15 or b=5
Step-by-step explanation:
b=20-a
a(20-a)=75
20a-[tex]a^{2}[/tex] -75=0
-[tex]a^{2}[/tex]+20a-75=0
[tex]a^{2}[/tex]-20a+75=0
(a-5)(a-15)=0
a-5=0 or a-15=0
a=5 or a=15
b=15 or b=5
(:
Answer:
Step-by-step explanation:
a + b = 20
Sum of roots = 20
ab = 75
Product of roots = 75
x² - (a +b) x + ab = 0
x² - 20x + 75 = 0
Sum = coefficient of x = -20
Product = 75
Factors = 15 , 5 {15*5 = 75 & 15 +5 = 20}
x² - 15x - 5x + 75 = 0 {Rewrite the middle term}
x(x - 15) - 5(x - 15) = 0
(x - 15) (x - 5)=0
x - 15 = 0 ; x -5 = 0
x = 15 ; x = 5
a = 15 ; b= 5

SALES Cars and trucks are the most popular vehicles. Last year, the number of
cars sold was 39,000 more than three times the number of trucks sold. There
were 216,000 cars sold last year. Write an equation that can be used
Answer:
39,000+3x=216,000
Step-by-step explanation:
brainliest please
The equation that can be used is 216,000 = 3T + 39,000 and the number of trucks sold last year is 59,000.
Given,
Number of cars sold last year = 216,000
The number of cars sold last year = 39,000 more than three times the number of trucks sold.
Let the number of trucks sold last year = T
Write the equation of the number of cars sold last year.
The number of cars sold last year = 39,000 more than three times the number of trucks sold.
216,000 = 3T + 39,000
Find the number of trucks sold last year.
We have,
216,000 = 3T + 39,000
Subtracting 39,000 on both sides.
216,000 - 39,000 = 3T + 39,000 - 39,000
177,000 = 3T
Divide 3 on both sides.
177,000 / 3 = 3T / 3
59,000 = T
The number of trucks sold last year is 59,000.
Thus the equation that can be used is 216,000 = 3T + 39,000 and the number of trucks sold last year is 59,000.

(EASY) In a rectangle, the length is 5 metres more than the width The perimeter of the rectangle is 70 metres Calculate the measurments for the length and width
Answer:
15 m and 20 m
Step-by-step explanation:
Let the width be x
Length = x + 5
Perimeter = 2(l + b)
70 = 2(x + 5 + x)
70/2 = 2x + 5
35 = 2x + 5
35 - 5 = 2x
30 = 2x
30/2 = x
15 = x
Length = x + 5 = 20 m
Breadth = x = 15 m
Find the measure of unknown angle
Answer:
Step-by-step explanation:
z = 102 degree (opposite angles of a parallelogram are equal)
z + x + 34 = 180 degree 9sum of adjacent angles of a parallelogram is 180 degree)
102 + x + 34 = 180
x = 180 - 136
x = 44 degree
y + 102 + x = 180 degree (sum of interior angles of a triangle is 180 degree)
y + 102 + 44 = 180
y = 180 - 146
y = 34 degree
Answer:
x = 44°, y = 34°, z = 102°
Step-by-step explanation:
The opposite angles of a parallelogram are congruent , then
∠ z = 102°
Consecutive angles are supplementary , then
x + 34° + 102° = 180°
x + 136° = 180° ( subtract 136° from both sides )
x = 44°
∠ y = 34° ( alternate angle

Answer:
Natalie.
Step-by-step explanation:
there is a constant pattern in the cost of shirts and the number of shirts that can be bought.
for every 1 shirt you pay $15.
thus, to determine the amount you pay for 2 shirts.
2(X)=Y {y= the total cost of 'n' shirts,X= the cost of 1 shirt.}
so this can be expressed as n15=Y
3 shirts therefore will be 3($15)= $45

Each big square below represents one whole What percent is represented by the shaded area?
Answer:
186%
Step-by-step explanation:
Looking at the squares, we can see that the first one has been completely shaded. That means that it is 100% shaded.
The second square has 86 out of 100 squares shaded, so that means that it is 86% filled.
Therefore 186% is filled by the shaded area.
