Answer:
m = 5
Step-by-step explanation:
Rewrite problem
m + 2m + -4m = -5
Combine like terms
-1m = -5
Divide -1 on both sides
-1m = -5/-1
m = 5
Check answer
5 + 2(5) +-4(5) = -5
5+ 10 + -20
-5 = -5

tia is swimming at a constant rate in a lake
Answer:
Step-by-step explanation:
If you wanted to figure out how long it would take her to get there it would be the distance she swims divided by her speed.
if you wanted to figure out how much her speed is, it would be the distance she swims divided by her speed.
If you wanted to figure out how long the distance is, you would multiply her speed and how long it took to get their.

Find the area of semi circle , π = 3, d = 12
Answer:
120cm *squared*
Step-by-step explanation:
A = π r² to find a circle
half of diameter is radius so 12/2 = 6
3 x 6 (squared) = 108
we found the half circle then add 12
so we make a semi circle
108 + 12= 120
answer 120 cm *squared*

what is the exterior angle?
The value of x° is 22° and exterior angle is 25.
Step-by-step explanation:
l can prove like this,
Here,2x°+(103-x)°=(6x-7)°...Being exterior angle
or,2x°+103°-x°=6x°-7°
or,x°+103°=6x°-7°
or,103°+7°=6x°-7°
or,5x°=110°
or,x°=110°÷5=22°
Now,
x°=22°
(6x-7)°=(6×22-7)°=125°
Mary has $32 to buy food and play games at the county fair. Suppose the food cost $8.00. Write and solve an inequality to find the most he can spend on games.
Answer:
$24 > $8
Step-by-step explanation:
Well if Mary has $32 and the food estimate costs $8 then the inequality would be written as $24 > $8. So Mary would have 24 dollars to play games.

3(4x+2) + 2(x-1)
Distribute by multiplying into the bracket
=12x + 6 + 2x - 2
Group like terms by adding and subtracting
= 14x + 4
Answer:
1) Multiply and expand the brackets:
12x + 6 + 2x - 2
2) Combine like terms (combine terms that have an x together, and those that don't together.)
14x + 4
If the question wanted you to simplify the expression, then 14x + 4 is your answer. However, to solve for x, you could equate the expression to 0, but I'm not too sure of this part.
14x + 4 = 0
14x = - 4
x = - 4/14
x = - 2/7

Anthropologists approximate the height of a primate by the size of its humerus (the bone from the elbow to the shoulder) using the equation
H = 1.2L + 27.8,
where L is the length of the humerus and H is the height, in inches, of the primate.
An anthropologist estimates the height of a primate to be 60 in. What is the approximate length of the humerus of this primate? Round to the nearest tenth of an inch.
in
Answer:
26.83
Step-by-step explanation:
H=1.2L + 27.8
60=1.2x+27.8
minus 27.8 from both sides
32.2=1.2x
divide both sides by 1.2
x=26.83
In AXYZ, X = 7.7 inches, y = 4.2 inches and z=7.3 inches. Find the measure of Y to
the nearest degree.
Answer:
32.38°
Step-by-step explanation:
In AXYZ, X = 7.7 inches, y = 4.2 inches and z=7.3 inches. Find the measure of Y to
the nearest degree.
We solve using Cosine rule
Y = arc cos( x² + z² - y²/2xz)
x = 7.7 inches
z = 7.3 inches
y = 4.2 inches
Y = arc cos( 7.7² + 7.3² - 4.2²/2 × 7.7 × 7.3)
Y = 32.38°

(2). Given, 556 + 336 = 826
By calculating 556 + 336 = 892
Hence, False
(3). Given, 458 - 248 = 238
By calculating 458 - 248 = 210

A bag contains 6 yellow counters, 3 green counters and 2 red counters. What is the probability that the first counter taken is red?
Answer:
Yellow counters = 6
Green counters = 3
Red counters = 2
Total number of counters = 6 + 3 + 2 = 11
Probability that the 1st counter taken is red
= Number of red counters/ total number of counters
= 2/11
