✎Question:Amirah is 4 years elder than Priya and Shirley is 2 years younger than Priya. If the sum of their ages is 47, find their respective ages ✔
Answer:
Priya's age = 15
Amirah's age = 19
Shirley's age = 13
Step-by-step explanation:
Let x be the age of Priya.
According to the question,
Amirah's age = x + 4
Shirley's age = x - 2
Their sum is 47.
So,
x + 4 + x + x - 2 = 47
3x + 2 = 47
3x = 47 - 2
3x = 45
x = 45/3
x = 15
So,
Priya's age = 15
Amirah's age = 15 + 4 = 19
Shirley's age = 15 - 2 = 13
Answer:
Priya is 15 years old
Amirah is 19 years old and
Shirley is 13 years old
Step-by-step explanation:
let Amirah =x
let Priya = y
let Shirley = s
so we have
x= 4+y
s=y-2
x+y+s =47
we have x= 4+y
4+y+y+s=47
4+2y+s=47
2y+s=43
s-y=-2 (MULTIPLY BY NEGATIVE 1)
y-s =2
2y+s= 43
by solving simultaneously we get
3y= 45
y=15
x= 4+y
x=19
s=y-2
s= 13
so Priya is 15 years old
Amirah is 19 years old and
Shirley is 13 years old

work out the size of angle x
Answer:
∠x = 117°
Step-by-step explanation:
supplement of ∠101° = 79°
all triangle interior angles add up to 180°
180° - 79° - 38° = 63°
the supplementary angle to 63° is 117°

4. An equilateral triangle has a perimeter of 60 cm. Find the exact
altitude of the triangle.
Step-by-step explanation:
GIVEN:-The Perimeter of Equilateral triangle = 60cm
UNDERSTANDING THE CONCEPT:-According to the question,
To find the height of the triangle,
Perimeter of Equilateral triangle = Area of Equilateral triangle.
FORMULA USED:-[tex]60 = \frac{ \sqrt{3} }{4} a {}^{2} \\ [/tex]
REQUIRED ANSWER:-[tex]60 \times 4 = \sqrt{3a {}^{2} } [/tex]
[tex]a {}^{2} = 240 \sqrt{3} \\ [/tex]
[tex]a = 120 \sqrt{3} cm[/tex]
SO, The Exact height of the triangle is 120√3cm.Which word could describe the relationship of the lines
containing the points (1, 6) and (1, 3)?

The difference of b and 4 is at most 15.
Answer:
b - 4 ≤ 15
b ≤ 19
Step-by-step explanation:
The statement "at most" typically means no more than, so the inequality sign would have to be "less than or equal to"
To solve for be all you would do is add 4 to both sides to get b by itself.
b - 4 ≤ 15
b - 4 + 4 ≤ 15 + 4
(-4 + 4 cancels itself out)
(15 + 4 = 19)
b ≤ 19
Using the LSRL model, estimate the volume of a gas 2.5, 4.5, and 6.5 atmospheres
Answer:
Brett is working in the chemistry lab trying to determine if he can predict the volume of three different gases (nitrogen, oxygen, and carbon dioxide) based upon the pressure applied to them. He kept all other characteristics of the gases constant. Brett performed the following analysis:

What is the probability of drawing an even number or a
multiple of 3?
Answer:
0.7
Step-by-step explanation:
2,3,4,6,8,9,10 are the possible choices.
∴P(even no. or multiple of 3)
= 7/10
Answer:
7/10 or 70%
Step-by-step explanation:
1 no
2 yes
3 yes
4 yes
5 no
6 yes
7 no
8 yes
9 yes
10 yes
7/10 are even or multiples of 3, therefore you have a 70% chance of drawing one of them

Answer: 25%
Step-by-step explanation:
Let's take our given numbers
20% you win both checkers and chess against your friend
30% you win against your friend in chess
Now we take both probability's 20% and 30%
We are know working with a probability out of 200%
Let's add 20% and 30%
20%+30%=50%
Now 50% of 200% is

Use the quadratic formula to find the solution to the quadratic equation given below. x^2-3x+9/4 =0
Answer:
[tex] x = \dfrac{3}{2} [/tex]
Step-by-step explanation:
x^2-3x+9/4 =0
Multiply both sides by 4 to get rid of the fraction.
4x^2 - 12x + 9 = 0
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] x = \dfrac{-(-12) \pm \sqrt{(-12)^2 - 4(4)(9)}}{2(4)} [/tex]
[tex] x = \dfrac{12 \pm \sqrt{144 - 144}}{8} [/tex]
[tex] x = \dfrac{12}{8} [/tex]
[tex] x = \dfrac{3}{2} [/tex]
Quadrilateral ABCD is a parallelogram. What is BC?
Answer:
BC = 36 ≅ (AQ+QD)
Step-by-step explanation:
1. Identify potential angles
∠Q≅90˚ so ∠B = 60˚ + 60˚ and ∠C = 30˚+30˚
2. Two isosoceles triangle
18=AB=AQ
18=CD=DQ
3. BC = AQ+QD
BC = 18+18
BC = 36
What are the measures of ∠1 and ∠2? PLEASE ANSWER
m∠1 = 58.2°, m∠2 = 75.5°
m∠1 = 67.4°, m∠2 = 104.5°
m∠1 = 75.5°, m∠2 = 67.4°
m∠1 = 104.5°, m∠2 = 58.2°
9514 1404 393
Answer:
(b) m∠1 = 67.4°, m∠2 = 104.5°
Step-by-step explanation:
It is easiest to find angle 2 first, then make your answer selection based on that.
The exterior angle 121.8° is the sum of the remote interior angles 17.3° and angle 2. Then ...
angle 2 = 121.8° -17.3° = 104.5° . . . . . . . matches the second choice
__
Angle 2 is an exterior angle of the top triangle. It, too, is the sum of the remote interior angles:
104.5° = angle 1 + 37.1°
angle 1 = 104.5° -37.1° = 67.4°
Answer:
C!
Step-by-step explanation:
m∠1 = 75.5°, m∠2 = 67.4°
5x−y=10 3x+y=14 please solve the system of equations and show your work
Answer:
x = 3, y = 5
or (3,5) in coordination point form.
Step-by-step explanation:
We are going to solve the system of equations by combining two equations. To do that, we isolate y-term.
[tex] \large{\begin{cases} 5x - y = 10 \\ 3x + y = 14 \end{cases}}[/tex]
Convert both equations to slope-intercept form.
[tex] \large{ \begin{cases} y = 5x - 10 \\ y = - 3x + 14 \end{cases}}[/tex]
Then combine both equations
[tex] \large{5x - 10 = - 3x + 14} \\ \large{5x + 3x = 10 + 14} \\ \large{8x = 24} \\ \large{x = 3}[/tex]
Substitute x = 3 in one of given equations. I will substitute x = 3 in y = 5x-10
[tex] \large{y = 5x - 10} \\ \large{y = 5(3) - 10} \\ \large{y = 15 - 10} \\ \large{y = 5}[/tex]
Hope this helps!

when can you combine like terms?
when can you NOT combine like terms?
( do not put the definiton of like terms i only need these questions answered)
Answer:
You can combine like terms when they have the same variable, same category, or same coefficient. You CANNOT combine like terms when they have none of the attributes listed above. For example, you can combine 7x and 20x, just like you can combine 3 and 4, but you can't combine 3x & 5(x^2), or 9x and 73.
