Answer:
Step-by-step explanation:
4x + 3y = 6 -----------------(I)
4x - y =2 ---------------------(II)
Multiply (II) by (-1) and then add
(I) 4x + 3y = 6
II) *(-1) - 4x + y = - 2 {Now add, x will be eliminated}
4y = 4
y= 4/4
y= 1
Plugin y =1 in equation (I)
4x +3*1 = 6
4x + 3 = 6
4x = 6- 3
4x = 3
x = 3/4
Answer:
( [tex]\frac{3}{4}[/tex], 1 )
Step-by-step explanation:
Given the 2 equations
4x + 3y = 6 → (1)
4x - y = 2 → (2)
Subtract (2) from (1) term by term to eliminate x
4x - 4x + 3y - (- y) = 6 - 2, that is
4y = 4 ( divide both sides by 4 )
y = 1
Substitute y = 1 into either of the 2 equations and solve for x
Substituting into (1)
4x + 3(1) = 6
4x + 3 = 6 ( subtract 3 from both sides )
4x = 3 ( divide both sides by 4 )
x = [tex]\frac{3}{4}[/tex]
solution is ( [tex]\frac{3}{4}[/tex], 1 )

The base of a rectangle is x. Its height is 6x + 25. Its area is 25. Write an equation that represents the area of the rectangle. (HINT start with the formula for area and fill in the given information) Solve your equation for x. All answers must be in integer or fraction form.
Answer:
x = -5 or 5/6
Step-by-step explanation:
The base of a rectangle is x. Its height is 6x + 25. Its area is 25. Write an equation that represents the area of the rectangle. (HINT start with the formula for area and fill in the given information) Solve your equation for x. All answers must be in integer or fraction form.
Area of a rectangle = Base × Height
From the above question:
25 = x × (6x + 25)
25 = 6x² + 25
Converting to algebraic expression
6x + 25x - 25 = 0
Factoring we have
(6x−5)(x+5) = 0
x+ 5 = 0
x = -5
6x - 5 = 0
6x = 5
x = 5/6
Therefore:
x = -5 or 5/6

Maria can alone we ave a basket in 4 hour and Ju lia can wea ve a basket in 6 hour . how mu ch time would it take if they work together to get a wea ve.
1 basket
15 basket
Answer:
[tex] \bold{1) 2 \frac{2}{5} hours} \\ 2)36 \: hours}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:fractionlet's solve:in 4 hours Maria weve 1 basket
in 1 hour Maria weve ¼ basket
in 6 hours Ju lia weve 1 basket
in 1 hour J ulia weve ⅙
in 1 hour Maria and J ulia can weve
[tex] \sf \frac{1}{4} + \frac{1}{6} \\ \sf = \frac{6 + 4}{24} \\ = \sf \frac{10}{24} \\ \sf \frac{5}{12} [/tex]
[tex]\frac{5}{12}[/tex] basket can be weved in 1 hour by Maria and J ulia
1 basket can be weved in
[tex] \sf 1 \div \frac{5}{12} \\ \sf 1 \times \frac{12}{5} \\ \sf2 \frac{2}{5} \: hours [/tex]
by Maria and J ulia
therefore
15 basket can be weved in
[tex] \frac{12 \times 15}{5} \\ 12 \times 3 \\ 36 \: hours[/tex]
Answer:
2.4 hours for 1 basket
36 hours for 15 baskets
Step-by-step explanation:
The formula to determine the time working together is
1/a + 1/b = 1/c where a and b are the times alone and c is the time together
1/4 + 1/6 = 1/c
Multiply each side by 12c since that is the common denominator
12c(1/4 + 1/6 = 1/c)
3c + 2c = 12
5c = 12
Divide by 5
5c/5 = 12/5
c =2.4 hours
This is the time for 1 basket working together
Now if they need to make 15 baskets together, multiply by 15
15 * 2.4 hours = 36 hours

One of the tokens for a board game is a circle containing 5 congruent triangles, as modeled below.
Which measurement is closest to the area in square centimeters of the token not covered by the triangles?
25.76 cm2
2.5 cim2
110.6 cm2
28.27 cm2
Answer:
b
Step-by-step explanation:
The solution is Option A.
The area of the token not covered by the triangles is 25.76 cm²
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
Given data ,
Let the area of the token not covered by triangles be A
Let the area of the triangle be T
Now , the height of the triangle h = 1 cm
The base of the triangle b = 1 cm
The area of the triangle = 1/2 x l x b
Substituting the values in the equation , we get
Area of the triangle T = 1/2 cm²
The number of triangles = 5
The area of 5 triangles = 5 x Area of the triangle
The area of 5 triangles = 5/2 cm²
The area of 5 triangles = 2.5 cm²
Now , the radius of the circle r = 3 cm
The area of the circle = πr²
Substituting the values in the equation , we get
Area of the circle = 3.14 x 3 x 3
Area of the circle = 28.26 cm²
Now , the area of the token not covered by triangles
A = Area of the circle - area of 5 triangles
Substituting the values in the equation , we get
The area of the token not covered by triangles A = 28.26 - 2.5
The area of the token not covered by triangles A = 25.76 cm²
Therefore , the value of A is 25.76 cm²
Hence , the area of the token without triangles is 25.76 cm²

It takes 45 min for Faucet A to fill a tank, and it takes Faucet B 63 min. How many minutes will it take the two faucets to fill the tank together?
Answer:
the total minutes taken together is 26.25 minutes
Step-by-step explanation:
The computation of the number of minutes that required to fill the tank together is shown below:
[tex]\frac{1}{45} + \frac{1}{63} = \frac{1}{x}\\\\\frac{7 + 5 }{315} = \frac{1}{x} \\\\\frac{12}{315} = \frac{1}{x} \\\\12x = 315\\x = 26.25[/tex]minutes
Hence, the total minutes taken together is 26.25 minutes

Answer:
1. 16π
2. 112π
3. 351.68
Step-by-step explanation:
Area of a circle = πr^2
Substitute...
=4^2π
=16π
To find the how much fluid it can hold, just basically find its volume. To do that, you mutiply the area of the base by the height. So...
16π*7=122π
You then just subsitute π by 3.14 so...
122(3.14)=351.68
