ach case:
(ii) (+5) + (+2)
(v) (-5) + (-2)
(viii) (+6) + (-3)
(xi) (-4) + (+8)
illustrate each of th
Answer:
Step-by-step explanation:
(+5) + (+2) = +7
If both numbers have same sign, add and the result will have the common sign
v) (-5) + (-2) = (-7)
Both numbers have 'negative sign'. So, add and the result will have the 'negative sign'
Viii) (+6) + (-3) = +3
Both numbers have different sign. So, subtract and the result will have the sign of the bigger number. Here the bigger number is '6' and its sign is 'positive'. so, the result will have positive sign
xi) (-4) + (+8) = +4
Both numbers have different sign. So, subtract and the result will have the sign of the bigger number. Here the bigger number is '8' and its sign is 'positive'. so, the result will have positive sign

7 t - shirts and a hat cost 67.00
5 t - shirts and a hat costs 49.00
How much does a hat cost?
How much does a t - shirt cost?
Answer:
Hat costs 4.00
T-Shirt costs 9.00
Step-by-step explanation:
Let the t-shirt be t and the hat be h
7t+h=67
5t+h=49
Equating by eliminating the h and subtracting
the two equations,
2t=18
t=9.
If t =9 in 5t + h= 49 then
5×9+h=49
45+h=49
h=4
simplify each expression.

Answer:
1,3,4
Step-by-step explanation:
6x-2y=10 slope intercept form
Answer:
To do this we just solve for y. Subtract 6x from both sides. Divide both sides by -2. The line has a slope of 3.
Step-by-step explanation:
Here are the first four terms of a quadratic sequence, the nth term of this quadratic
sequence is an² + bn + c.
2, 12, 28, 50
Find the values of a, b and c.
(4 marks)
Answer:
a = 3, b = 1, c = - 2
Step-by-step explanation:
Substitute n = 1, 2, 3, 4 into the nth term and equate to the values , that is
a + b + c = 2 → (1)
4a + 2b + c = 12 → (2)
9a + 3b + c = 28 → (3)
16a + 4b + c = 50 → (4)
Subtract (1) from (2) to eliminate c
3a + b = 10 → (5)
Subtract (3) from (4) to eliminate c
7a + b = 22 → (6)
Subtract (5) from (6) to eliminate b
4a = 12 ( divide both sides by 4 )
a = 3
Substitute a = 3 into 5) and solve for b
3(3) + b = 10
9 + b = 10 ( subtract 9 from both sides )
b = 1
Substitute a = 3 and b = 1 into (1) and solve for c
3 + 1 + c = 2
4 + c = 2 ( subtract 4 from both sides )
c = - 2
Then
a = 3, b = 1, c = - 2
and y = 3n² + n - 2 ← explicit formula

Troy has $35 to pay for a movie ticket and then buy comic books. Each comic books costs $3, the
movie ticket costs $10. Which equation can be used to determine how many comic books, b, Troy can buy?
A.10b + 3 = 35
B.3b + 35 = 10
C.3b + 10 = 35
D.10b + 35
Answer:
the answer is 3
Step-by-step explanation:
b will be used to determine how many books he bought since he is only buying one movie ticket the equation would be 3b + 10 = 35

What is the measure of ∠J?
127°
92°
39°
141°
Answer:
39°
Step-by-step explanation:
A triangle always equals 180° so you have to subtract the other two angles from 180 to find the measure of J
180°-88°-53°= 39°
Plz help it is 10 points
Oh please first if the rectangle was compete, it's area would be 8.
The area of the missing triangle is [tex]\frac{2*2}{2}[/tex]=2.
8-2=6

A 35-foot ladder is leaning against the side of a building and is positioned such that the base of the ladder is 21 feet from the base of the building. How far above the ground is the point where the ladder touches the building?
Answer:
height = 28 feet
Step-by-step explanation:
using the Pythagorean theorem:
height = 35² - 21²
height² = 1225 - 441 = 784
height = 28 feet
The number of vertices in a prism is twice the number of vertices of one of the bases. How many vertices does one of the bases of a regular prism with 14 faces and 36 edges have?
Answer:
24
Step-by-step explanation:
The computation of the number of vertices does one of the base of regular prism is shown below:
V + F = E + 2
V + 14 = 36 + 2
V + 14 = 38
V = 38 - 14
= 24

Are the ratios 2:1 and 10:5 equivalent? yes or no
Answer:
Yes
Step-by-step explanation:
10/5 = 2 and 5/5 = 1
Answer:
Yes
Step-by-step explanation:
To find out if the ratios are equivalent you need to simplify both of them. The ratio 2:1 is already simplified all the way. You know this because 2 and 1 have no GCF (greatest common factor) besides 1. However, 10:5 is not all the way simplified. The GCF is 5, so divide both sides by 5. This equals 2:1. The ratio 2:1 is equal to 2:1; therefore, they must be equivalent.
