Answer:
8.5
Step-by-step explanation:
The required value of the number is 8.5 which is twice the difference between a number and 5 is 7.
How to solve this problem?To solve this problem, we first need to express the given information in terms of a mathematical equation.
The statement "Twice the difference of a number and 5 is 7" can be represented as the equation 2 × (x - 5) = 7, where x is the number we're trying to find.
Next, we can solve this equation to find the value of x. To do this, we can first distribute the 2 on the left-hand side of the equation to get 2x - 10 = 7.
Then, we can add 10 to both sides of the equation to get 2x = 17.
Finally, we can divide both sides of the equation by 2 to get x = 17/2 = 8.5.
Therefore, the required value of the number is 8.5.

Kiran and Clare like to race each other home from school. They run at the same speed, but Kiran's house is slightly closer to school than Clare's house. On a graph, their distance from their homes in meters is a function of the time from when they begin the race in seconds.
As you read the graphs left to right, would the lines go up or down?
What is different about the lines representing Kiran's run and Clare's run?
What is the same about the lines representing Kiran's run and Clare's run?
Answer:
1. Down.
2. Clare's line would be higher because she begun further away from her house.
3. The lines would have the same slope since they are going the same speed.

Step 1: Define
3 - 6(z - 2)
z = -2
Step 2: Evaluate
Substitute in z: 3 - 6(-2 - 2)(Parenthesis) Subtract: 3 - 6(-4)Multiply: 3 + 24Add: 27By substituting value of z = - 2 in 3 - 6(z - 2), we get :
[tex] \tt : \implies 3 - 6(z - 2) = 3 - 6((-2) - 2)[/tex]
[tex] \tt : \implies 3 - 6(z - 2) = 3 - 6(-2 - 2)[/tex]
[tex] \tt : \implies 3 - 6(z - 2) = 3 - 6(- 4)[/tex]
[tex] \tt : \implies 3 - 6(z - 2) = 3 + 24[/tex]

Mallory bought pizza and soda for her End of Summer party. If she spent $12.57 on the
sodas and $10.95 for each pizza, how many pizzas did she buy if she spent $89.22?
Which equation models this scenario?
12.57 + 10.95 = 89.22
10.95x + 12.57 =
89.22
12.57x + 10.95 =
89.22
89.22x - 10.95 = 12.57
Answer:
10.95x + 12.57 = 89.22

HELP ME PLEASEEEEE THIS IS SO HARD
Answer:
4. Given
6. Definition of verticle angles
7. Algebra/part-whole-postulate/sum of interior angles in a triangle/CPTCTC (Corresponding parts of congruent triangles are congruent)
Step-by-step explanation:
number 4 is just...given because it shows that they're both right angles
6, it's literally the definition of verticle angles
7, since we know that angle TQU and angle RSU are congruent and angle QUT and SUR are congruent, if we subtract those from 180, that means those two angles also have to be congruent
Also, the two triangles are congruent by LA or ASA, so CPCTC would also work
Part-whole-postulate, same reasoning as algebra.
Sum of interior angles in a triangle, same as algebra.
Hope this helped, let me know if you have any questions.

0.5y -2 2/5 = 1/2y +2.4
Answer:
No solution
Step-by-step explanation:
Move all the variables to one side and all the numbers to the other side.
0.5y-2*2/5=1/2y+2.4
-2*2/5=1/2y+2.4-0.5y
-2*2/5-2.4=0
thus there is no solution
What is the ratio in which the point P(3/4,5/12) decides the line segment joining points A(1/2,3/2) and B(2,-5)
Given:
The point [tex]P\left(\dfrac{3}{4},\dfrac{5}{12}\right)[/tex] divides the line segment joining points [tex]A\left(\dfrac{1}{2},\dfrac{3}{2}\right)[/tex] and [tex]B(2,-5)[/tex].
To find:
The ratio in which he point P divides the segment AB.
Solution:
Section formula: If a point divides a segment in m:n, then the coordinates of that point are,
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Let point P divides the segment AB in m:n. Then by using the section formula, we get
[tex]\left(\dfrac{3}{4},\dfrac{5}{12}\right)=\left(\dfrac{m(2)+n(\dfrac{1}{2})}{m+n},\dfrac{m(-5)+n(\dfrac{3}{2})}{m+n}\right)[/tex]
[tex]\left(\dfrac{3}{4},\dfrac{5}{12}\right)=\left(\dfrac{2m+\dfrac{n}{2}}{m+n},\dfrac{-5m+\dfrac{3n}{2}}{m+n}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{3}{4}=\dfrac{2m+\dfrac{n}{2}}{m+n}[/tex]
[tex]\dfrac{3}{4}(m+n)=\dfrac{4m+n}{2}[/tex]
Multiply both sides by 4.
[tex]3(m+n)=2(4m+n)[/tex]
[tex]3m+3n=8m+2n[/tex]
[tex]3n-2n=8m-3m[/tex]
[tex]n=5m[/tex]
It can be written as
[tex]\dfrac{1}{5}=\dfrac{m}{n}[/tex]
[tex]1:5=m:n[/tex]
Therefore, the point P divides the line segment AB in 1:5.

Answer:
(a)(b)=0.45
a/b=0.8
Step-by-step explanation:
a=0.6
b=0.75
(a)(b)=(0.6)(0.75)=0.45
a/b=0.6/0.75=0.8
Answer:
a*b = 0.5
a/b = 0.888...
Step-by-step explanation:
0.6666... = 2/3
a*b = 2/3 * 3/4 = 1/2 = 0.5
a/b = (2/3) / (3/4) = 8/9 = 0.888...

Find the area:
HELP PLEASE
Answer:
Area = 30.3 ft²
Step-by-step explanation:
Area = area of a semicircle + area of a rectangle
= (½*πr²) + L*W
Where,
radius (r) = ½ of 4 = 2 ft
Length (L) = 6 ft
Width (W) = 4 ft
Plug in the values
Area = (½*π*2²) + (6*4)
Area = 30.3 ft² (nearest tenth)

Lines a and b are parallel.
What is the measure of angle s?
Enter your answer in the box
S=
Answer:
22 degrees
Step-by-step explanation:
The angle that measures 158 degrees and angle u are supplementary angles, meaning they add up to 180 degrees.
Angle s and angle u are corresponding angles, meaning that they are congruent.
This means that the angle that measures 158 degrees and angle s are supplementary as well. Knowing this, we can construct the following equation:
[tex]180=158+s[/tex]
Subtract both sides by 158
[tex]180-158=158+s-158\\22=s[/tex]
Therefore, angle s has a measure of 22 degrees.
I hope this helps!
