What property do we use when we find equivalent fractions?
Answer:
It's called the cross multiply rule. The rule is shown below: This formula says that if the numerator of one fraction times the denominator of the other fraction equals the denominator of the first fraction times the numerator of the second fraction, then the fractions are equivalent.
Step-by-step explanation:
If ∠ A and ∠ B are supplementary angles and ∠ A is seventeen times as large as ∠ B, find the measures of ∠ A and ∠ B.
supplementary angles = 180°

All 5 students in Mrs.Awful’s class got 50 for the test For the next test, one of the students got 100 but the remaining students all got 50. What it the average grade in the class now?
Answer:
60
Explanation:
the formula for calculating the average grade would be the total score of all students ÷ the number of students. in this case, that would be:
(100 + 50 + 50 + 50 + 50) ÷ 5
= 300 ÷ 5
= 60
so, the average grade is 60.

If x=7 then which answers would I circle? A. X + 7 = 17 b. 7 = 17 - x c. 70 = 10x d. X/35 = 5 e. 15x = 105
Answer:
C. 70 = 10x
E. 15x = 105
Step-by-step explanation:
x = 7
Using method of elimination;
A. X + 7 = 17
Substituting the value of x;
7 + 7 ≠ 17 (Incorrect option)
B. 7 = 17 - x
Substituting the value of x;
7 ≠ 17 - 7 (Incorrect option)
C. 70 = 10x
Substituting the value of x;
70 = 10 * 7 (Correct option)
D. X/35 = 5
Substituting the value of x;
7 / 35 ≠ 5 (Incorrect option)
E. 15x = 105
Substituting the value of x;
15 * 7 = 105 (Correct option)

See bolded below.
Step-by-step explanation:
As you said, you only need help with no. 2:
a) Check the attachments for the lines
b) The equations are, respectively:
y = -4x + 1 [intersects parabola at 1 point]
Check:
[tex]\begin{bmatrix}y=\left(x-2\right)^2-3\\ y=-4x+1\end{bmatrix}[/tex]
[tex]\begin{bmatrix}-4x+1=\left(x-2\right)^2-3\end{bmatrix}[/tex]
[tex]\begin{bmatrix}-4x+1=x^2-4x+1\end{bmatrix}[/tex]
[tex]x^2=0, x = 0[/tex]
[tex]y=-4\cdot \:0+1 = 1[/tex]
[tex]y=1,\:x=0[/tex]
The point of intersection would be (0, 1)
y = -4x + 3 [intersects parabola at 2 points]
Check:
[tex]\begin{bmatrix}y=\left(x-2\right)^2-3\\ y=-4x+3\end{bmatrix}[/tex]
Subtract the 2 equations,
[tex]y=\left(x-2\right)^2-3\\-\\\underline{y=-4x+3}\\y-y=\left(x-2\right)^2-3-\left(-4x+3\right),\\0=x^2-2\\x = \sqrt{2}, x = - \sqrt{2} \\\\\mathrm{Plug\:the\:solutions\:}x=\sqrt{2},\:x=-\sqrt{2}\mathrm{\:into\:}y=\left(x-2\right)^2-3[/tex]
[tex]\begin{pmatrix}x=\sqrt{2},\:&y=3-4\sqrt{2}\\ x=-\sqrt{2},\:&y=3+4\sqrt{2}\end{pmatrix}[/tex]
Therefore the points of intersection are (√2, 3-4√2) and (-√2, 3+4√2) respectively
And finally we have the equation y = - 4x. It doesn't intersect the parabola.
c) The y-intercepts of such graphs are all less than or equal to 0.

ADC is a triangle.
AED and ABC are straight lines.
EB is parallel to DC.
Angle EBC=148°
Angle ADC=63°
Work out the size of angle EAB.
You must give a reason for each stage of your working out.
Answer:
[tex]\angle EAB = 85[/tex]
Step-by-step explanation:
Given
[tex]\angle EBC = 148[/tex]
[tex]\angle ADC = 63[/tex]
See attachment for triangle
Required
Find EAB
[tex]\angle AEB = \angle ADC = 63[/tex] --- corresponding angles
[tex]\angle ABE + \angle EBC = 180[/tex] --- angle on a straight line
So:
[tex]\angle ABE + 148 = 180[/tex]
This gives:
[tex]\angle ABE =- 148 + 180[/tex]
[tex]\angle ABE =32[/tex]
Considering: [tex]\triangle ABE[/tex]
[tex]\angle ABE +\angle AEB +\angle EAB = 180[/tex] --- angles ina triangle
So:
[tex]32 +63+\angle EAB = 180[/tex]
[tex]95+\angle EAB = 180[/tex]
Collect like terms
[tex]\angle EAB = 180-95[/tex]
[tex]\angle EAB = 85[/tex]

This year Adeele paid £465 for her car insurance. This is an increase of 20% on last year's payment. How much did Adele pay last year?
Answer:
Insurance cost (last year)= £387.5
Step-by-step explanation:
Giving the following information:
Insurance cost= £465
Increase growth rate= 20% = 0.2
To calculate the cost of insurance last year, we need to use the following formula:
Insurance cost (last year)= insurance cost / (1 + insurance growth rate)
Insurance cost (last year)= 465 / (1 + 0.2)
Insurance cost (last year)= £387.5
The amount that Adele pay last year was:£387.5.
Car insurance:Using this formula
Amount paid= Insurance cost / (1 + Insurance growth rate percentage)
Where:
Insurance cost= £465
Increase growth rate percentage=20% or 0.20
Let plug in the formula
Amount paid= £465 / (1 + 0.20)
Amount paid= £465/1.20
Amount paid= £387.5
Inconclusion the amount that Adele pay last year was:£387.5.
