Answer:
y = 6
x = 2
Step-by-step explanation:
rearrange the first equation in terms of x
x = (y - 2)/2
substiute x in the second equation
y = -5[(y-2)/2] +16
Now simpilify and solve for y
y = (-5y + 10)/2 +16
y = -5/2y + 5 + 16
y + 5/2y = 5 + 16
3.5y = 21
y = 6
Now substitue y in the first equation to solve for x
x = (6 - 2)/2
x = 2
Answer:
25%
Step-by-step explanation:
Put in proportion:
14/56 = p/100
Simplify:
1/4 = p/100
Multiply 4 x 25:
4 x 25 = 100
Do same to the other side:
1 x 25 = 25
p = 25
25%
Answer:
g > 2t , 15 t + 9g >500 are the inequalities which can be used to find the value of g and t.
Step-by-step explanation:
Earning at grocery store = $9 per hour
Earning as tutor = $15 per hour
Let the number of hours she tutors = t
and the number of hours she works at grocery store = g
Total earning she wants = $500
Now, the earning from tuition = 15 t
Earning from Grocery store= 9g
According to the question:
g > 2t
15 t + 9g >500
Hence, both the above inequalities can be used to find the value of g and t.
The equivalent expressions are 3(6x - 3) = 72 and 18x - 9 = 72
<h3>Equations and expressions</h3>
Given the equation below as shown;
3/5(30x - 15) = 72
Expand
3/5(30x) - 3/5(15) = 72
90x/5 - 15/5 = 72
3(6x - 3) = 72
Expand
18x - 9 = 72
Hence the equivalent expressions are 3(6x - 3) = 72 and 18x - 9 = 72
