solve simultaneous equation....4x-5y and 2x+y=4
[tex]4x - 5y = 20and2x + y = 4[/tex]
how to solve simultaneous equation?
Answer:
( [tex]\frac{20}{7}[/tex], - [tex]\frac{12}{7}[/tex] )
Step-by-step explanation:
4x - 5y = 20 → (1)
2x + y = 4 → (2)
subtract 2x fro both sides in (2)
y = 4 - 2x → (3)
substitute y = 4 - 2x into (1)
4x - 5(4 - 2x) = 20 ( distribute parenthesis and simplify left side )
4x - 20 + 10x = 20
14x - 20 = 20 ( add 20 to both sides )
14x = 40 ( divide both sides by 14 )
x = [tex]\frac{40}{14}[/tex] = [tex]\frac{20}{7}[/tex]
substitute this value into (3)
y = 4 - 2([tex]\frac{20}{7}[/tex] ) = [tex]\frac{28}{7}[/tex] - [tex]\frac{40}{7}[/tex] = - [tex]\frac{12}{7}[/tex]
solution is ( [tex]\frac{20}{7}[/tex] , - [tex]\frac{12}{7}[/tex] )
Convert 8 ft to inches
Answer: 96 inches

on the world globe, the distance between city A and city B is 6.875 inches. The two cities are actually 4469 miles apart. On the same globe, what would be the distance between cities C and city D, two cities that are actually 4761 miles apart? Use a proportion to solve this problem.
Answer:
7.32 in (nearest hundredth)
or 7.324 in (nearest thousandth)
Step-by-step explanation:
inches : miles
A : B = C : D
6.875 : 4469 = y : 4761
6.875 / 4469 = y / 4761
y = (6.875 / 4469) x 4761
y = 7.32 in (nearest hundredth)
y = 7.324 in (nearest thousandth)
Answer:
the distance between cities C and D is 7.3242 inches.
given:
city A and city B is 6.875 inches, actually 4469 miles apart. city C and city D is x inches, actually 4761 miles apartsolve similarities:
[tex]\hookrightarrow \sf \dfrac{6.875}{x} = \dfrac{4469}{4761}[/tex]
[tex]\hookrightarrow \sf 4469(x) = 6.875*4761[/tex]
[tex]\sf 4469x = 32731.875[/tex]
[tex]\hookrightarrow \sf x = \dfrac{32731.875}{4469}[/tex]
[tex]\hookrightarrow \sf x = 7.3242[/tex]

Which statement about x2 + 10x = 11 is true?
Equations are statements that have equal values, when compared
The true statement about [tex]x^2 + 10x = 11[/tex] are x = 1 and x = -11
How to determine the true statementThe equation is given as:
[tex]x^2 + 10x = 11[/tex]
Rewrite as:
[tex]x^2 + 10x - 11 = 0[/tex]
Expand
[tex]x^2 + 11x - x - 11 = 0[/tex]
Factorize
[tex]x(x + 11) -1( x + 11) = 0[/tex]
Factor out x + 11
[tex](x -1)(x + 11) = 0[/tex]
Solve for x
x = 1 or x = -11
Hence, the true statement about [tex]x^2 + 10x = 11[/tex] are x = 1 and x = -11

pls help me i will mark as brilliant

1a) Firstly, lets start by expanding the brackets. x × x is x². So x(x+1) = x² + x. Then we do the second part. 2 × x = 2x and 2 × 1 = 2. Now we have
x² + 3x + 2.
Now what we do is simplify through quadratic formula. We look at the last digit which is 2. What two numbers multiplies to give you 2? 2 and 1. 2 x 1 = 2 and 2 + 1 = 3. Our second number is 3 so this is the right amount. so now we just put the two factors together. (x + 1)(x+2). This is the answer.
b) I have explained above and so am just gonna write the answers. After expanding we get x² + 2x + 1. We get simplify to
= (x + 1)(x+1)
c) y² + 3y + 4. This cannot be simplified into the format so we leave it like this.
d) = 0.

Jordan needs 5 pounds of chips for a party. The bags he is buying are 24 oz each. According to the number line, how many bags will he need to buy to have at least 5 pounds?
Answer:
4 bags
Step-by-step explanation:
First, 5 pounds is equal to 80 ounces.
Then, when looking at the number line, we see that 80 ounces is right before "96" to represent 4 of the 24 oz bags. This means that he will need to buy 4 bags, according to the number line.
We can also do it the mathematical way.
-> 80 ounces / 24 ounce bags = 3 [tex]\frac{1}{3}[/tex].
We cannot buy [tex]\frac{1}{3}[/tex] of a bag, so we round up to 4 bags.

Notice that the plane figures above are congruent with each other, so that
#6x/8 = 4/16
16x = 8 × 4
16x = 32
x = 2
#7x/5 = 48/6
6x = 5 × 48
6x = 240
x = 40
#8x/7 = 90/10
10x = 7 × 90
10x = 630
x = 63
#93/x = 10/40
10x = 3 × 40
10x = 120
x = 12
Using the information of each pair and thus calculate the value of X, then:
6)x= 2
7)x=40
8)x=63
9)x=12
So calculating the value of X, we have:
6) x/8 = 4/16
16x = 8 × 4
16x = 32
x = 2
7) x/5 = 48/6
6x = 5 × 48
6x = 240
x = 40
8) x/7 = 90/10
10x = 7 × 90
10x = 630
x = 63
9)3/x = 10/40
10x = 3 × 40
10x = 120
x = 12

A scoop of ice cream in the shape of a whole sphere sits in a right cone. The radius of the ice cream scoop is 1.5 cm and the radius of the cone is 1.5 cm.
a. What is the volume of the scoop of ice cream? *Show all your work.*
b. How tall must the height of the cone be to fit all the ice cream without spilling if it melts? *Show all your work.*
The volume of the scoop of ice cream is 14.14 cm³.
The height of the cone that would fit all the ice cream is 6 cm.
What is the volume of the scoop of ice cream?In order to determine the volume of the scoop of ice cream, the formula for the volume of a sphere would be used.
Volume of a sphere = 4/3 x pi x r^3

Solve the system of equations:
x-y=4
4x-7z=24
4y+z=8
Answer: x=6, y=2, z=0
Step-by-step explanation:
We know from the third equation that z=8-4y
and from the first that x=y+4
Substitute into the 2nd equation,
4(y+4)-7(8-4y)=24
4y+16-56+28y=24
32y-40=24
32y=64
y=2
Meaning x=6 and z=0.
