Answer:
x = 6.7
Step-by-step explanation:
We know that 3.5 + x = 10.2, so if we do inverse operations we can find out the value of x.
10.2 - 3.5 = 6.7
we can check our work by substituing it back in the equation for x
6.7 + 3.5 = 10.2
so now we know that x = 6.7. I hope this helps :)
Answer: x=6.7
Step-by-step explanation:
x+3.5=10.2
-3.5 -3.5
x= 6.7

Suzette deposited $800 into a bank account earning simple interest of 2.5% each year. After 5 years, how much interest had her account earned?
Answer:
[tex]\boxed {\boxed {\sf \$ 100.00}}[/tex]
Step-by-step explanation:
The formula for simple interest is
[tex]I=prt[/tex]
where p is the principal, r is the rate, and t is the time.
The principal, or initial amount is $800 and the time is 5 years The interest rate is 2.5%, but we must convert to a decimal.
Divide by 100 or move the decimal place two spots to the left.
2.5/100=0.025 or 2.5 ⇒ 0.25 ⇒ 0.025Substitute the known values into the formula.
[tex]p= 800 \\r= 0.025 \\t= 5[/tex]
[tex]I= (800)(0.025)(5)[/tex]
Multiply.
[tex]I=20(5)\\I=100[/tex]
After 5 years, Suzette's account has earned $100.00

Find the value of x.
Pleaseeee I need helppp!!!!!!
Answer:
x = 38
Step-by-step explanation:
The measure of a vertex angle outside a circle = ½(difference of intercepted arcs)
Thus:
m<S = ½(UV - TW)
m<S = 34°
UV = (3x - 2)°
TW = (x + 6)°
Plug in the values into the equation
34 = ½((3x - 2) - (x + 6))
34 = ½(3x - 2 - x - 6)
34 = ½(2x - 8)
Multiply both sides by 2
34*2 = 2x - 8
68 = 2x - 8
68 + 8 = 2x (addition property of equality)
76 = 2x
76/2 = x (division property of equality)
38 = x
x = 38

An isosceles trapezoid has a perimeter of 49 centimeters. Its shorter base measures 8
centimeters and its longer base measures 11 centimeters. The two remaining sides have the
same length
what is that length?
Answer:
15
Step-by-step explanation:
11+8=19
49-19=30
because its an isosceles trapezoid the missing sides are equal to each other so we just have to divide 30 by 2
30/2=15
the answer is 15

Jerome earned an 80% on his math test. If there were thirty-five questions on the test, how many questions did he answer correctly? Explain your work
Answer:
28 questions
Step-by-step explanation:
80% is 80 out of 100, so we can represent it as 80/100.
80 / 100 = y / 35
We need to find the value of y.
To do this we can cross multiply, with a method I like to call the butterfly method.
80 y
100 35
80x35=2800
Therefore, 100 times y equals 2800.
So we divide 2800 by 100.
2800/100=28.
Therefore, y equals 28.
y=28.

What is the solution for inequality on the model
Answer:
option 1 is correct. that is the answer
Find the inequality represented by the graph
Answer: y<x-1
Step-by-step explanation:
So first we have to find the blue line. y=mx+b is the equation. For slope it is 0--1 which is 1 and 1-0 which is 1 so the slope is just one or x now we need to find the y intercept which is just -1. So y<(is less than)x-1! Hope this helps :)
