Answer:
x= -1
Step-by-step explanation:
since y is -5 then we would put that in the second equation:
2x - 4(-5) = 18
then it’s:
2x + 20 = 18
Then we subtract 20 from both sides
2x = -2
Last we divide both by 2 and we get x = -1
Answer:
x= -1
Step-by-step explanation:
2x + 20 =18
2x = 18 - 20
x = -1

What are fractional linear equations and how one can solve it?
Linear equations which are in the form of fractions are referred as fractional linear equations.
an equation containing the unknown in the denominator of one or more terms (as a/x + b/(x + 1) = c)
It is frequently simplest to eliminate the fraction in the first step when dealing with fractions incorporated into linear equations. Typically, this entails locating the fraction's LCD and multiplying each term in the entire equation.
Solution:
Given:
Money left with charles = 12 pesos
Money spent = 2/3 of the total amount.
Find:
Total Money he had at first = ?
Step-1:
Let x denote the total amount of money he had at the beginning.
After spending 2/3 of his money he is left with 1/3 of part of his money.
Step-2:
So the equation can be written as:
1x/3 = 12
x = 36
Hence the total money he had at the beginning was 36 pesos.

What is the approximate volume of the cone? Use 22/7 for π. Enter your answer in the box.
volume of a cone is 132 cubic centimeter.
What is volume of cone?The volume of a cone is defined as the amount of space or capacity a cone occupies. The volume of a cone formula is given as one-third the product of the area of the circular base and the height of the cone.
Volume of cone V = [tex]\frac{1}{3} \pi r^{2} h[/tex]
Given
Radius of cone r = 3 cm
Height of cone h = 14 cm
[tex]\pi[/tex] = [tex]\frac{22}{7}[/tex]
Volume of cone V = [tex]\frac{1}{3} \pi r^{2} h[/tex]
V = [tex]\frac{1}{3}[/tex] × [tex]\frac{22}{7}[/tex] × [tex]3^{2}[/tex] × [tex]14[/tex]
V = 22 × 3 × 2
V = 132 cubic centimeter
Hence, volume of a cone is 132 cubic centimeter.

Find the volume of a cone that has a radius of 4 centimeters and a height of 19
centimeters.
(Use 3.14 for pi and round the answer to the nearest hundredth.)
Answer:
Volume of the cone = 318.19 cubic cm
Step-by-step explanation:
Volume of a cone = 1/3πr²h
r is the radius = 4cm
h is the height = 19cm
Substitute into the formula
Volume of a cone = 1/3π(4)²(19)
Volume of a cone = 1/3* 3.14 * 16 * 19
Volume of a cone = 954.56/3
Volume of a cone = 318.19 cubic cm

Which of the following is the correct order when multiplying two binomials?
Inner, first, last, outer
First, outer, inner, last
Outer, last, first, inner
Last, inner, outer, first
Please help.
Answer:
A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial.
Step-by-step explanation:
The correct order when multiplying two binomials will be First, outer, inner, and last. Then the correct option is B.
What is binomial?The binomial is a polynomial of two-term only. For example, x + 5 where x and 5 are two separate terms.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
Let the two expressions are (a + b) and (c + d). Then the multiplication of the expressions will be given as,
⇒ (a + b) x (c + d)
⇒ a(c + d) + b(c + d)
⇒ ac + ad + bc + bd
The correct order when multiplying two binomials will be First, outer, inner, and last. Then the correct option is B.

Komisyon (9-6) 12) Bir araba satıcısı, bir haftalık araba satışlarının% 2,5'ini ve saatine 30 dolar veriyor, haftalık satışları 100.000 S $ idi ve 40 saat çalıştı. Hafta boyunca toplamda ne kadar kazandı?
Cevap:
3700 ABD doları
Adım adım açıklama:
Haftalık satış = 100.000 $
Haftalık satışlarda kazanılan yüzde =% 2,5 = (0,025 * 100.000 ABD Doları) = 2500 ABD Doları
Saatlik kazanç = 30 $
Çalışılan saat sayısı = 40 saat
Çalışılan saat için kazanç = 40 * 30 $ = 1200 $
Toplam kazanç:
Haftalık satış yüzdesi + çalışılan saat için kazanç
(1200 ABD doları + 2500 ABD doları) = 3700 ABD doları
