Step-by-step explanation:
Given
[tex]5x-3y=14[/tex] -- (1)
[tex]3x-5y=2[/tex] -- (2)
Required
Find x and y
We'll solve this using elimination method.

Answer:
Streamers cost 2.50 and balloons cost 1.25.
Step-by-step explanation:
Pls mark brainliest.
Answer:
Balloon : $1.25
Streamer : $ 2.50
Step-by-step explanation:
Form simultaneous equations.
Let streamer be represented by ------------s
Let balloons be represented by ------------b
So the equations will be;
3s + 2b = 10 ----------------i
2s + 1b = 6.25---------------ii
Make the terms with s equal by multiplication
[3s + 2b = 10 ]2
[2s + 1b = 6.25]3
Perform subtraction
6s + 4b = 20
6s + 3b = 18.75
b = 1.25 ---------iii
Use iii in ii as;
2s + 1b = 6.25
2s + 1.25 = 6.25
2s = 6.25 - 1.25
2s = 5.00
s= 5.00 / 2
s= 2.5
Hence ; a balloon is $1.25 and a streamer is $2.5
Which represents a function?
Answers
Answer:
[tex] \boxed{ \text{Option \: D}}[/tex]
Step-by-step explanation:
All the relations are not functions. We can determine ( identify ) whether a relation is function or not by drawing a vertical line intersecting the graph of the relation. This is called vertical line test.
If the vertical line intersects the graph of a relation at one point , the relation is a function .If it cuts at more than one point , it is not a function. It means that if there are more points of the graph of a relation of a vertical line , same first component ( pre - image ) has more images ( second component ) which is not the function by definition.--------------------------------------------------
Let's check all of the options :
☐ Option A :
The vertical line cuts the graph at two points. So , the graph does not represent a function.☐ Option B
No! This is also not a function as the vertical line cuts the graph at two points.☐ Option C
Nah! This too can't be called a function as the vertical line cuts the graph at two points.☑ Option D
Yep! The vertical line cuts the graph at one point. Thus , the graph represents a function.Yayy!! We found our answer. It's ' Option D '.

4. The ratio of the measures of the three angles in a triangle is 7:8:5, what is the
measure of the smallest angle?
Your answer
Answers
Step-by-step explanation:
let the angles be ' 7x, 8x and 5x'
as we know, the sum of all the angles of a triangle is 180 degree, so,
7x + 8x + 5x = 180
20 = 180
x = 180/2
x = 90 degrees
7x = 7 × 90 = 630 degree
8x = 8 × 90 = 720 degrees
5x = 5 × 90 = 540 degrees
therefore, 5x is the smallest degrees

Hey need this ASAP I’ve work through almost just need this one
Answers
Answer:
He must score an 86 or more on his third test.
Step-by-step explanation:
An average is calculated by the sum of the numbers divided by the total number (#) of numbers (if that makes sense). Knowing this, we can write an algebraic equation in order to find the answer. Let x equal the unknown number.
John's previous test scores and this test score now must be at least an average of 90 or more. Therefore, the equation would be [tex]\frac{86+98+x}{3} \geq 90[/tex]. Isolate x to find the answer:
[tex]\frac{86+98+x}{3}\geq 90\\ \frac{184+x}{3} \geq 90\\184 + x \geq 270\\x \geq 86[/tex]
Therefore, he needs to get at least a 86 or higher.
Can the Pythagorean Theorem be used to find a distance in the coordinate plane?
Answers
Answer:
Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, a2+b2=c2 a 2 + b 2 = c 2 , is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse.
Step-by-step explanation:

Answer:
Yes it can be used because there is a right angle and by using 3 points u form a right triangle and then u will can find distance

Roger has two golden retrievers, Sadie and Buddy. buddy weighs 14 pounds more than Sadie. If their total weight is 136 pounds, how much does Sadie weigh
Answers
Answer:
Sadie weighs 61 pounds.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
Sadie's weight is x.
Buddy's weight is y.
Buddy weighs 14 pounds more than Sadie.
This means that [tex]y = x + 14[/tex]
Their total weight is 136 pounds.
This means that
[tex]x + y = 136[/tex]
Since [tex]y = x + 14[/tex]
[tex]x + x + 14 = 136[/tex]
[tex]2x = 122[/tex]
[tex]x = \frac{122}{2}[/tex]
[tex]x = 61[/tex]
Sadie weighs 61 pounds.

Mr. Jones charged Roberta $105 for parts and $25 per hour for labor to repair her bicycle. He spent 2 hours repairing her bike. Which expression would be used to correctly calculate the amount Roberta owes him?
a.(2 × 25) + 105
b.(105 x 2) + (25 x 2)
c.2 x (25 + 105)
d.2 x 25 × 105
Answers
Answer:
a.(2 × 25) + 105
Step-by-step explanation:
Let the number of hours spent repairing the bike = x
Mr. Jones charged Roberta $105 for parts and $25 per hour for labor to repair her bicycle.
Therefore, our algebraic expression
= $25× x + $105
= 25x + 105
We were told in the question that He spent 2 hours repairing her bike.
Hence:
25 × 2 + 105
Therefore, the correct option is option a
a.(2 × 25) + 105
