Write yes or no if the value given makes the equation true.
1. w – 2 = 5; w = 7
2. 5t = 15; t = 4
3. x + 8= 10; x = 945
4. 5 = x + 3; x = 2
Answer:
1. yes
2.no
3.no
4.yes
Step-by-step explanation:
just use division, addition, subtraction
Answer:
1. yes
2. no
3. no
4. yes
Step-by-step explanation:
1. substitute w with 7 --> (7) - 2 = 5 --> 5 = 5; true
2. substitute t with 4 --> 5(4) = 15 --> 20 does not = 15; false
3. substitute x with 945 --> (945) + 8 = 10 --> 953 does not = 10; false
4. substitute x with 2 --> 5 = (2) + 3 --> 5 =5; true

But hopefully it's helpful.
Answer:
steps below
Step-by-step explanation:
if your problem is s²ⁿ = s²*²⁰ = s⁴⁰ (n replace your t)
s²ⁿ = 7⁴⁰ = 6366805760909027985741435139224001

A countertop is 11 feet long and 4 fee t wide.
What is the area of the countertop in square meters? Use the conversion 1 foot = 0.305 meter. Round your
final answer to 2 decimal place
Answer:
4.09m^2
Step-by-step explanation:
A countertop is 11 feet long and 4 fee t wide.
Using the conversion
1foot = 0.305 meter
11fet = 11(0.305)
11feet = 3.355 m
4 feet= 4 * 0.305
4feet = 1.22m
Area of the countertop = Length * Width
Area of the countertop = 3.355 * 1.22
Area of the countertop = 4.0931m^2
Hence the required area is 4.09m^2 to 2 decimal places
The number of students at a high school was decreased by 30% to 420 after the senior students graduated how many students were at the high school before the decrease
Answer:
Step-by-step explanation:
s(1-30/100)=420
s(100-30)/100=420
s(70/100)=420
s(7/10)=420
7s=4200
s=600

Show all your work! Thank you!
Answer: B
Step-by-step explanation:
x = van
y = bus
12x + 9y = 456
1x + 2y = 83
(Simplify equations)
9y = -12x + 456
y = -1.3x + 456/9
2y = -x + 83
y = -1/2x + 41.5
(Find x)
-1.3x + (456/9) = -.5x + 41.5
0.8x = 9.16
(Round)
x = 11
(Find y by plugging x in)
y = -1/2(11) + 41.5
y = -5.5 + 41.5
y = 36
(Check)
12(11) + 9(36) = 456
132 + 324 = 456
1(11) + 2(36) = 83
11 + 72 = 83

find the length of a missing side of the triangle around your nearest tenth
Using the Pythagorean theorem:
14^2 = 8^2 + x^2
196 = 64 + x^2
Subtract 64 from both sides:
132 = x^2
Take the square root of both sides:
X = 11.49
Rounded to nearest tenth = 11.5
Answer:
missing side = 11.5
Step-by-step explanation:
[tex]a^{2} = c^{2} - b^{2}[/tex]
[tex]a^{2} = 14^{2} - 8^{2}[/tex]
[tex]a^{2} = 196 - 64[/tex]
[tex]a^{2} = 132[/tex]
[tex]\sqrt{a^{2} } - \sqrt{132}[/tex]
a = 11.489
round to the nearest tenth:
11.489 = 11.5

If m\angle VXW=28\degreem∠VXW=28°, what is the measure of arc VW?
Answer:
m(arc VW) = 56°
Step-by-step explanation:
m∠VXW = 28°
By inscribed angle theorem,
"Length of intercepted arc measures the double of the inscribed angle"
m(arc VW) = 2m(∠VXW)
m(arc VW) = 2(28°)
m(arc VW) = 56°
Therefore, measure of arc VW is 56°.
