Answer:
x=9.5, y=5.75
Step-by-step explanation:
2x-5=14, 3x+2y=40
focus on 2x-5=14 first:
2x-5=14 (add 5 to both sides) 2x=19(divide both sides by 2) x=9.5
Now subtitute x into the second equation and find y:
3(9.5)+2y=40(simplify) 28.5+2y=40(subtract 28.5 on both sides) 2y=11.5(divide both sides by 2) y=5.75

Step-by-step explanation:
Answer:
Yes Of course.This always confuses but you are correctIf you need further explanation, don't hesitate to ask mePlease, I need a Brainliestwhat is 7(1 - 8n)???
Answer:
7-56n
Step-by-step explanation:
By using the distributive property you multiply the 7 to the 1 which equals 7. Then you distribute the 7 to the -8n which gives you -56n becaus emultiplying a negative and a possitive gives you a negative.
The required solution is -56n+7.
It is required to find the solution.
What is algebra?A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Given:
Rearrange terms
7(1 - 8n)
=7(-8n+1)
Then distribute by multiplying 7 we get,
-56n+7
Therefore, the required solution is -56n+7.

The endpoints of PQ are P(2, 0) and Q (4, 2). Find the coordinates of midpoint PQ.
Answer:
Step-by-step explanation:
Parameterize the ellipse as (acos∙,bsin∙). Take points P:=(acosp,bsinp) and Q:=(acosq,bsinq) on the ellipse, with midpoint M:=(P+Q)/2.
If |PQ|=2k, then
a2(cosp−cosq)2+b2(sinp−sinq)2=4k2
The coordinates of M are

The formula for the volume V of a cylinder is , where r is the radius of the base and h is the height of the cylinder. Select the formula for h. Then select the height of a cylinder with a volume and a base with a radius of 3 cm
Answer:
h = 4 cmStep-by-step explanation:
V = π r² h
where r = 3 cm
V = 36π cm³
solve for h
plugin values into the formula:
36π = π 3² h
h = 36π
π 3²
h = 4 cm
A globe has a diameter of 14 inches. Find the volume of the globe. Round your answer to the nearest tenth.
Answer:
1436.8 in³ (nearest tenth)
Step-by-step explanation:
A globe is in the shape of a sphere.
[tex]volume \: of \: sphere = \frac{4}{3} π {r}^{3} [/tex]
Diameter= 2 ×radius
radius of globe
= 14 ÷2
= 7 inches
Volume of globe
[tex] = \frac{4}{3} π {(7}^{3} ) \\ = 1436.8 \: in^{3} \\ (nearest \: tenth)[/tex]
Step-by-step explanation:
We have given that diameter of globe (sphere) is 14 inches,Then it's radius is 14/2 = 7 inches :]To find the volume of sphere we have to use the given below formula :]
[tex] \boxed {\underline{ \underline{\bigstar\:\: \sf Volume \: of \: sphere = \dfrac{4}{3} \pi r^3 \: \: \bigstar}}} \\ \\ [/tex]
☯ [tex]\underline{\boldsymbol{According\: to \:the\: Question\:now :}} [/tex]
[tex]:\implies \sf Volume \: of \: sphere = \dfrac{4}{3} \times 3.14 \times 7 \times 7 \times 7 \: \: \bigg \lgroup \bf{putting \: \pi = 3.14} \bigg \rgroup \\ \\ [/tex]
[tex]:\implies \sf Volume \: of \: sphere = \dfrac{4}{3} \times 3.14 \times 343 \\ \\ [/tex]
[tex]: \implies \underline{ \boxed{ \sf Volume \: of \: sphere = 1436.0267 \: cubic \: inches}} \\ [/tex]

The area of Gateway National Recreation is about twenty-six thousand, six hundred and sixty-three hundredths. Which shows this number in standard form?
Answer:
B. 26,606.63
Step-by-step explanation:
The area of Gateway National Recreation Area is about twenty-six thousand, six hundred six and sixty-three hundredths. Which shows this number in standard form? A. 26,606.3 B. 26,606.63
C. 26,660.63 D. 26,666.3
Solution
Break down and writing in numerals of twenty-six thousand, six hundred six and sixty-three hundredths.
Twenty six thousand = 26,000
Six hundred six = 606
Sixty - three hundredth = 0.63
Adding
26,000 + 606 + 0.63
We have
26,606.63

Suppose the volume of a rectangular shopping cart basket is 12,090 cubic inches. If the length measures 31 inches and the width measures 19.5 inches, how high is the shopping cart basket?
Answer:
[tex]\boxed {\tt h=20\ inches}[/tex]
Step-by-step explanation:
The volume of a rectangular prism can be found using the following formula.
[tex]v=l*w*h[/tex]
We know that the volume is 12,090 cubic inches, the length is 31 inches, and the width is 19.5 inches.
[tex]v= 12,090 \ in^3\\l=31 \ in \\ w=19.5 \ in[/tex]
[tex]12,090 \ in^3= 31 \ in * 19.5 \ in * h[/tex]
Multiply 31 inches and 19.5 inches.
[tex]12,090 \ in^3= 604.5 \ in^2 * h[/tex]
We are trying to find h, therefore we must isolate it. h is being multiplied by 604.5 square inches. The inverse of multiplication is division. Divide both sides of the equation by 604.5 in²
[tex]\frac{12,090 \ in^3}{604.5 \ in^2}= \frac{604.5 \ in^2 *h}{604.5 \ in^2}[/tex]
[tex]\frac{12,090 \ in^3}{604.5 \ in^2}=h[/tex]
[tex]20 \ in =h[/tex]
The height of the shopping basket is 20 inches.

18- 12y = -22 -7y solve for y
Answer: y=8
Step-by-step explanation:
To solve for y, you want to use algebraic properties to isolate y.
18-12y = -22-7y [add both sides by 7y]
18-5y=-22 [subtract both sides by 18]
-5y=-40 [divide both sides by -5]
y=8
Now, we know that y=8.

24 is what percent of 49?
Answer:
48.97
Step-by-step explanation:
[tex] \tan(x ) = \frac{10}{60} [/tex]
How do I solve this?
tan(x) = 10/60
tan(x) = 1/6
tan(x) = a -> x = arctan(a) + πn
x = arctan(1/6) + πn
x = 0.165 + πn

What is 1 5/6 + 1/2?
A) 14/6
B) 17/12
C) 17/6
D) 25/12
Answer:
A) 14/6
Step-by-step explanation:
1 5/6 = 1 + 5/6 = 6/6 + 5/6 = 11/6
1/2 = 3/6
then:
1 5/6 + 1/2 = 11/6 + 3/6 = 14/6
