Answer:
Ahmed's left with $12
Step-by-step explanation:
step 1
Find out the cost of a water bottle
Let
x -----> the cost of a water bottle
y ----> the cost of the burrito
-----> equation A
-----> equation B
substitute equation B in equation A and solve for x
therefore
The cost of a water bottle is $2
step 2
Find out how much money does Ahmed have left
Let
x -----> the amount of money Ahmed originally had
we know that
The cost of a burrito and a water bottle is equal to one third of the amount of money Ahmed originally had
so
Solve for x
Multiply by 3 both sides
therefore
The amount of money Ahmed originally had was $18
If he spent 1/3 of his money
then
He's had 2/3 of the money left.
Multiply 2/3 by the amount of money Ahmed originally had
therefore
Ahmed's left with $12.
Answer:
<h2>b = 41 mm</h2>
Step-by-step explanation:
From the question
Area of a triangle is given by
where
b is the length of the base
h is the height
From the question
Area = 328 mm²
height = 16 mm
Substitute the values into the above formula and solve for the height
We have
Divide both sides by 8
We have the final answer as
<h3>b = 41 mm</h3>

Answer:
1.56
Step-by-step explanation:
7 divided by 9 = .777777777
move the dot over 2 spots to the right = 77.78%
77.78% of 2 = 1.5556
round the nearest hundredth = 1.56
Ii.First ,expand: 5(x-2)=32
5x-10=32
bring 10 to the other side (add it to 32)
5x=42
divide both sides by 5 to get x
x=42/5
x=8.4
iii.Expand 5+2(x+3)=21
5+2x+6=21
bring 5 and 6 to the other side
2x=21-5-6
2x=10 divide both sides by 2
x=5
The answer is A (360/53=6.8)
