Seclect all the sets of numbers that are possible values for x in the inequalit, x > - 8. { -10, -8, -6}. { -8, 0, 8}. { -9, 1, 7}. { -6, -4, -2}
Answer:
{ -6, -4, -2}
Step-by-step explanation:
Since x > - 8, x can be any number greater than - 8.
x = -7, -6, -5, -4,...
BUT, it can't be equal because it's not using this sign [tex]\geq[/tex]
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
1. { -10, -8, -6} can't be an inequality of x because it has -10, -8.
2.{ -8, 0, 8} can't be an inequality of x because of -8.
3.{ -9, 1, 7} can't be an inequality of x because -9 isn't greater than x.

Solve the system of equations
y=2/3x + 4
2x - 3y=3
A: Infinite Solutions
B: No Solution
C: (3,2)
D: (2,-3)
Answer:
B) no solution
Step-by-step explanation:
this can be solved by substitution method
y= ⅔x + 4. (equation 1)
and 2x-3y= 3. (equation 2)
substitute for y into equation 2
2x-3(2/3x + 4) = 3
2x - 2x -12=3
0=15
this is a no solution equation

Suppose that an individual has a body fat percentage of 16.2% and weighs 164 pounds. How many pounds of his weight is made up of fat? Round your answer to the nearest tenth.
Answer:
26.6 pounds
Step-by-step explanation:
Hope this helps :)
Have a great summer!! :)
Answer:
26.6 pounds
Step-by-step explanation:
You must find 16.2% of 164.
10%=16.4
5%=8.2
1%=1.64
0.1%=0.164
0.2%=0.328
16.4+8.2+1.64+0.328=26.568
rounded = 26.6 pounds

Saj has made 7 litres of curry sauce.
He wants to put the curry sauce intojas.
Each jar can be completely filled with 375 millilitres of cury sauce.
Saj wants to completely fill as many jars as possible with cury sence.
How many jars can be fill?
Answer:
18 jars can be filled completely.
Step-by-step explanation:
7L=7000ml
1 jar contain 375 ml
375ml can be filled in 1 jar
375ml=1 jar
1 ml = 1/375 jar
7000 ml = 7000× 1/375 jar
7000ml= 18.67 jar
hence 18 jars can be filled completely.
The total number of jars that can be filled with sauce is A = 18 jars
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Saj has made 7 litres of curry sauce = 7000 mL
And , each jar can be completely filled with 375 millilitres of cury sauce
So , the number of jars A = 7000 / 375
On simplifying the equation , we get
A = 18.67 jars
Hence , the number of jars is A = 18 jars

A student had 500 of water in a water bottle . She drank 30 % of the water before soccer practice practice drank of the water much water to the nearest milliliters does the student have left in the bottle ?
Answer:
piece of cake, she got 350ml of water left
Step-by-step explanation:
lets find out what 10% of 500 is, which is 50
so 20% is 100
we do 10% 3 times, so 50x3=150
500-150=350
it is 350

Shirts are 5% off. The original price of one shirt is $15. What is the total cost, in dollars, of a shirt at the sale price, including a 10% sales tax
Answer:
$15.75
Step-by-step explanation:
[tex]\frac{y}{15} :\frac{5}{100}[/tex]
y × 100 = 5 × 15
100y = 75
100y ÷ 100 = 75 ÷ 100
y = 0.75
$15 - $0.75
$14.25
[tex]\frac{y}{15} :\frac{10}{100}[/tex]
y × 100 = 10 × 15
100y = 150
100y ÷ 100 = 150 ÷ 100
y = 1.5
$14.25 + $1.50
$15.75

the ratio of boys to girls is 4:7
how many students are in the class?
9514 1404 393
Answer:
33
Step-by-step explanation:
The total number of ratio units is 4+7 = 11. If each one stands for an integer number of students, that number is a multiple of 11 between 24 and 40. The only such number is 3×11 = 33.
There are 33 students in the class.

GE = 26
Step-by-step explanation:
OP = 16 + 9 = 25
PE - OG = 7
Using Pythagorean theorem,
(GE)^2 = (OP)^2 + (PE - OG)^2
=(25)^2 + (7)^2
= 625 + 49
= 674

Step-by-step explanation:
The revenue of the company is given by the equation R = x (1000 – 4x), where R is the revenue of the company in dollars when thy sell x units of a product. How many units of the product should they sell to make a revenue of $60,000
Answer:
100 or 150 units of the product.
Step-by-step explanation:
R = x(1000-4x)
What is the value of x if R = 60,000?
x(1000-4x) = 60000
-4x^2 + 1000x = 60000
x^2 - 250x = -15000
x^2 - 250x + 15000 = 0
Factorize:
(x-100)(x-150) = 0
x-100 = 0 V x-150 = 0
x = 100 V x = 150
