Answer:
3 times - 2,times 8-13
You solve the ones in the bracket first
(the rule of BODMAS)
So 8-13 first, then
-2times 8-13,then
Then you get your answer
What is the angle measure for
Answer:
x = 6
∠PQR = 29
Step-by-step explanation:
Sum of interior angles in a triangle is 180,
15x - 4 + 4x + 5 + 65 = 180
15x + 4x + 5 - 4 + 65 = 180
19x + 1 + 65 = 180
19x + 66 = 180
19x = 180 - 66
19x = 114
x = 114 / 19
x = 6
∠PQR = 4x + 5
Substitute x = 6,
∠PQR = 4 ( 6 ) + 5
= 24 + 5
∠PQR = 29

Solve this equation. Enter your answer in the box. -5/6 - 2/3e=24
Answer:
[tex] - \frac{5}{6} - \frac{2}{3} e = 24 \\ - 1.2 - 1.5e = 24 \\ - 1.5e = 24 + 1.2 \\ - 1.5e = 25.2 \\ e = - \frac{25.2}{1.5} \\ e = - 16.8 [/tex]
Write 360 as a product of primes.
Use index notation when giving your answer
Answer:
First, find any number that divides evenly into 360. Perhaps the number that comes to mind, since it ends in a 0, is 10. Since 10 divides into 360 and the result is 36, you can write 360 = 10*36.

Damian is taking a multiple choice test with a total of 40 points available. Each question is worth exactly 4 points. What would be Damian's test score (out of 40) if he got 4 questions wrong? What would be his score if he got xx questions wrong?
Answer:
36/40 or 90%
Step-by-step explanation:
First convert it to a fraction, which in this case is 36/40.
To find the percentage, we need to find an equivalent fraction with the denominator of 100. Multiply both numerator & denominator by 100.
36/40 × 100/100
= (36 × 100/40) × 1/100 = 90/100
Therefore, the answer is 90%.
If you are using a calculator, simply enter 36÷40×100, which will give you 90 as the percentage.

2x + y = 5
6x + 3y = 25
inconsistent; one
consistent, dependent; one
consistent, dependent; infinite
inconsistent; none
HELP ASSAP PLS
Step-by-step explanation:
2x + y = 5 (times 3)
6x + 3y = 25
↓↓↓↓↓↓↓↓↓↓↓↓
6x + 3y = 15
6x + 3y = 25
→ No solution ←
2x+y=5
y=-2x+53y=-6x+15--(1)6x+3y=25
3y=-6x+25As slopes are equal lines are parallel
So no solutions

1) make q the subject of the formula 4(q+p)=5+7q
2) Make x the subject of the formula y=2a-bx^2
Answer:
1) [tex]q = \frac{4p}{3} -\frac{5}{3}[/tex]
2) [tex]x = \frac{\sqrt{b -y + 2a} }{b}[/tex]
Step-by-step explanation:
1) 4(q + p) = 5 + 7q
Multiply 4(q + p):
4q + 4p = 5 + 7q
4p - 5 = 7q - 4q
4p - 5 = 3q
[tex]\frac{4p}{3} - \frac{5}{3} = \frac{3q}{3}[/tex]
[tex]\frac{4p}{3} - \frac{5}{3} = q[/tex] or [tex]q = \frac{4p}{3} - \frac{5}{3}[/tex]

Which equation does the graph below represent?
A coordinate grid is shown. The x-axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y-axis values are from negative 10 to positive 10 in increments of 2 for each grid line. A line is shown passing through the ordered pairs negative 4, 8 and 0, 0 and 4, negative 8.
y = −2x
y = fraction negative 1 over 2x
y = 2x
y = fraction 1 over 2x
Answer:
y = -2
Step-by-step explanation:
The graph passes through (0,0) and (-1,2).
The equation of a line passing through the origin is of the form,
y = mx
We now substitute (-1,2) to obtain,
2 = -m
This implies that,
m = -2
The equation is
y = -2
