Step-by-step explanation:
f(x) = 2x + 5 = 45
2x + 5 = 45
2x = 45 - 5
2x = 40
x = 20
Answer:
f(x) = 2x + 5 = 45
2x + 5 = 45
5-25=2x
40=2x
x = 20
0.7 (3s + 4)-1.1s = 7.9
Answer:
s = 5.1
Step-by-step explanation:
[tex]0.7 (3s + 4)-1.1s = 7.9\\[/tex]
Multiply both sides of the equation by 10
[tex]0.7\left(3s+4\right)\cdot \:10-1.1s\cdot \:10=7.9\cdot \:10\\\\= 7\left(3s+4\right)-11s=79\\[/tex]
Expand
[tex]\mathrm{Expand\:}7\left(3s+4\right)-11s:\\\quad 10s+28[/tex]
Subtract 28 from both sides
[tex]10s+28-28=79-28[/tex]
Simplify
[tex]10s=51[/tex]
Divide both sides of the equation by 10
[tex]\frac{10s}{10}=\frac{51}{10}[/tex]
Simplify
[tex]s=\frac{51}{10}\\\\Decimal = 5.1[/tex]
help pls!!!how to solve it
Answer:
q = 5/6
Step-by-step explanation:
First, we distribute.
16q - 10 = 4q
Then, we combine like terms.
-10 = 4q - 16q
-10 = -12q
Finally, we divide -12 on both sides.
5/6 = q, or q = 5/6

Kaya rented a limousine for prom. The company charges a cleaning fee of $100 and an hourly rate of $45. Her total cost for the night was $437.50. For how many hours did Kaya rent the limousine?
Answer:
Number of hours= 7.5
Step-by-step explanation:
Giving the following information:
The company charges a cleaning fee of $100 and an hourly rate of $45.
Her total cost for the night was $437.50
First, we need to structure the total cost formula:
Total cost= 100 + 45*x
x= number of hours
437.5= 100 + 45x
337.5/45= x
x= 7.5
Number of hours= 7.5
Answer:
Kaya rented the limo for about 7.5 hours
Hope this helps! good luck :)
The product of two numbers is 37.03.If one number is 2.3,find the other.
Answer:
16.1
Step-by-step explanation:
37.03/2.3 = 16.1
Answer:
[tex]\boxed{\bold{\huge{\boxed{16.1}}}}[/tex]
Step-by-step explanation:
Let the first number be x and the second number be y
So, the condition is:
[tex]x * y = 37.03[/tex]
Given that x = 2.3
[tex]2.3 * y = 37.03[/tex]
Dividing both sides by 2.3
[tex]y = \frac{37.03}{2.3}[/tex]
[tex]y = 16.1[/tex]

Answer:
the measurement of C is 83° because AB = BE so B = A
180° (triangle ABE) - 57°(2) = 66°
180° (line AD) - 66° = 114°
180° (line BC) - 114° = 66° (angle E)
180° (Triangle DCE) - 66° - 31° = 83°

A survey showed that 4 out of 5 students own a bicycle. Based on this result, how many of the 800 students in a school own a bicycle? Use any strategy to solve.
Answer:
640 students
Step-by-step explanation:
We are told in the question that 4 out of every 5 students owns a bicycle
This also means , out of every 5 students only 1 does not have bicycle
Then we have a ratio of 4 : 1
This means a fraction of 4/5 students own a bicycle in a school
Based on this result, how many of the 800 students in a school own a bicycle?
This calculated as:
4/5 × 800
= 640 students
Therefore, 640 students out of 800 students own a bicycle

a metal block has the following dimensions height 2cm length 10cm width 5cm calculate the volume of the block
Answer:
100cm^3
Step-by-step explanation:
The volume of any cube or cuboid is calculate by simply multiplying the length by the width by the height.
So if our length is 10cm, our width is 5cm and our height is 2cm, then our volume is 10x5x2=100cm^3 (cubic centimeters-unit for volume.)
