Aldo is on his way on his car. He has driven 15 so far which is three-fifths of the way home. What is the total length of his drive
Answer:
25 is the total length
Step-by-step explanation:
Distance driven = 15
Which Is 3/5 of the way home
Total length of drive
The unknown = x which is the total length of his drive
From the statement in this question 15 is three-fifth of c
So we have this equation:
(3/5)x = 15
We divide both sides by (5/3) so that x can stand on its own
(3/5)(5/3)x = 15(5/3)
(15/15)x = 75/3
x = 25
The total length of the drive is 25

Answer:
C x=40, y=30
Step-by-step explanation:
Remember the opposite side of parallelogram is the same
so angle C and angle A is the same.
3x=120
divide both sides by 3 and you get 40
All parallelogram equal to 180 degrees so to find y
180=2y+120
-2y=120-180
-2y=-60 negative divide negative is positive.
y=30

Simplify each expression and evaluate it for x=3 13 . 3(2x+6)−(3x+1) The simplified expression is : The value of the expression for the given x is :
Answer:
Simplified expression; 3x + 17
The value of the function for the given value of x is 26
Step-by-step explanation:
Restructured
Simplify each expression and evaluate it for x=3, 3(2x+6)−(3x+1) The simplified expression is : The value of the expression for the given x is :
Given the expression;
3(2x+6) - (3x-1)
On simplification:
= 3(2x) + 3(6) -3x + 1
= 6x + 18 - 3x + 1
= 6x - 3x + 18-1
= 3x + 17
If x = 3
f(3) = 3(3) + 17
f(3) = 9 + 17
f(3) = 26
Note the question was re-structured since the given question was not too clear
What are the possible values of x?
2 possible values :)
Answer:
x = 3, x = 11
Step-by-step explanation:
Since PR is an angle bisector then it divides the opposite side into segments which are proportional to the other 2 sides, that is
[tex]\frac{PQ}{PS}[/tex] = [tex]\frac{QR}{SR}[/tex] , substitute values
[tex]\frac{x+1}{16}[/tex] = [tex]\frac{x-2}{x+1}[/tex] ( cross- multiply )
(x + 1)(x + 1) = 16(x - 2) ← expand left side using FOIL
x² + 2x + 1 = 16x - 32 ( subtract 16x - 32 from both sides )
x² - 14x + 33 = 0 ← in standard form
(x - 3)(x - 11) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 11 = 0 ⇒ x = 11

find the value of x in the triangle below
Answer:
x=109
Step-by-step explanation:
The angles inside of a triangle all add up to 180 degrees. So:
23+48+x=180
Simplify Like-Terms:
71+x=180
Subtract 71 from both sides:
x=109

Which inequality represents the following number line?
+
-10-9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
Select one:
a. x < -6
b.X > -6
C.XS-6
d. x > -6
Answer:
b. x > -6
Step-by-step explanation:
> [greater than], and < [less than] inequalities are not filled in because the value is not included, but is only greater or less than.
≥ [greater than or equal to], and ≤ [less than or equal to] inequalities are filled in because the value is included, and it is greater than or less than.
Given that there is an empty circle with an arrow moving in the positive direction from -6, the inequality must be a greater than, and since the value is -6, x > -6.

Mya and ERIC WORK IN A BAKERY . MYA HAS 3 TIMEA AS MUCH FLOUR AS ERIC .MYA HAS 15.81LB OF FLOUR .USE THE EQUATION 3F = 15.81 TO FIND HOW MUCH FLOUR ERIC HAS .
Answer:
5.27 lb
Step-by-step explanation:
Given that,
Mya has 3 times as much floor as Eric. Mya has 15.81 lb of floor. The relation is given by :
Let Eric has F floor.
3F = 15.81 ...(1)
We need to find how much flour Eric has.
Dividing both sides by 15.81.
F = 15.81/3
F = 5.27 lb
Hence, Eric has 5.27 lb of flour.
Marie purchased a $50.00 gift for a baby shower. She uses a coupon that offers 20% off. How much will Marie spend on the gift after the coupon?
Answer:
40
Step-by-step explanation:
so first we need to figure out how many money did she save
50*20% = 10 dollars
so she saved 10 dollars
then 50-10=40
so she paid 40 dollars
There are 11 books on a shelf. 4 of these books are new. The rest of them are used.
(a) What is the ratio of new books to used books?
(b) What is the ratio of all books on the shelf to used books?
Answer:
a. 4/11
b. 11-4= 7 used books. So the ratio of used books to all books is 11/7
Two square rooms have total floor area of 89cm².One room is 3m longer each way than the other,Find the dimension of the two rooms
Answer:
5 m
8 m
Step-by-step explanation:
Area of square = s² ; s = side length
Let the area of each room equal to x and y
x + y = 89cm²
If x = smaller room
y = x + 3 in dimension
Hence,
x² + (x + 3)² = 89
(x +3)(x +3) = x² + 3x + 3x + 9
x² + x² + 3x + 3x + 9 = 89
2x² + 6x + 9 = 89
2x² + 6x - 80 = 0
x² + 3x - 40 = 0
x² + 8x - 5x - 40 = 0
x(x + 8) - 5(x + 8) = 0
x + 8 = 0 ;
x - 5 = 0
x = - 8 or x = 5
Dimension can't be negative :
So, x = 5
Samller square = x = 5
Larger square = x + 3 = 5 + 3 = 8

Find the value of x in the isosceles triangle shown below.
please help owo
Answer:
10
Step-by-step explanation:
We will first take a right triangle and we will apply the pythagorean theorem to it. First, the base of the right triangle will be 12/2 which is 6; then, we will just use the theorem.
a^2+b^2 = c^2 (pythagorean theorem)
8^2+6^2 = c^2
100 = c^2
c = 10 because the square root of 100 is 10
in a class of 32 students the mean height of the 14 boys is 1.56 meters and the mean height of all 32 students is 1.151 meters. work out the mean height of girls
Answer: Hence, Mean height of the girls is: 1.48
Step-by-step explanation: It is given that:
in a class of 32 students .
the mean height of 14 boys is 1.56 and the mean height of all 32 students is 1.515.
Since there are 14 boys in a class.
So, number of girls is equal to (32-14)=18.
The mean height of 14 boys is 1.56.
Hence the sum of height of 14 boys is= 1.56×14=21.84
Similarly mean height of 32 students is 1.515.
Hence, sum of height of 32 students=1.515×32=48.48.
Let x denote the mean height of 18 girls.
Hence, sum of height of 18 girls is: 18 x.
Now,
18x+21.84=48.48
( since sum of height of girls and boys is equal to the sum of height of all the students)
so, 18x=48.48-21.84
18 x=26.64
Hence, x=1.48
Hence, Mean height of the girls is: 1.48
