Answer:
Solve the system of equations.
x = 1
y = 2
Step-by-step explanation:
Hope it is helpful....
[tex]5x + 2y = 9[/tex]
with given condition where y = 2.
Therefore, substitute the value of y in the equation.
[tex]5x + 2(2) = 9 \\ 5x + 4 = 9[/tex]
Solve the equation for x-term.[tex]5x = 9 - 4 \\ 5x = 5 \\ x = \frac{5}{5} \longrightarrow \frac{1}{1} \\ x = 1[/tex]
Check the answer by substituting both x-value and given y-value in the equation.[tex]5x + 2y = 9 \\ 5(1) + 2(2) = 9 \\ 5 + 4 = 9 \\ 9 = 9 \longrightarrow \bf{true} \: \green{ \checkmark}[/tex]
Hence, the value of x is 1.

Find x for brainliest
Answer:
4
Step-by-step explanation:
6/(6+6) = 5/(5+5) = (3x+5)/(5x+14) = 1/2
3x+5 = 1/2*(5x+14)
6x+10 = 5x+14
x = 4
If 1 is subtracted from a number and this difference is tripled the result is 23 more than the number
Answer:
The number is 13
Step-by-step explanation:
Let the number be y
1 is subtracted from the number. This can be written as:
y – 1
The difference is tripled. This can be written as:
3(y – 1)
The result of the difference tripled is 23 more than the number. This can be written as:
3(y – 1) = 23 + y
Thus, we can obtain the value of y as follow:
3(y – 1) = 23 + y
Clear bracket
3y – 3 = 23 + y
Collect like terms
3y – y = 23 + 3
2y = 26
Divide both side by 2
y = 26 / 2
y = 13
Thus, the number is 13.

HELP PLSSS ASAP!!!!!!!!
Answer:
x = 5.5
Step-by-step explanation:
PM = MR
4x - 12 = -2x + 21 {add 2x to both the sides}
4x - 12 + 2x = -2x + 2x + 21
6x - 12 = 21 {Add 12 to both sides}
6x - 12 + 12 = 21 + 12
6x = 33
x = 33/6
x = 5.5
Step-by-step explanation:
here,
4x-12 = -2x+21 4x+2x = 21+12 6x = 33 x = 33/6Please help.

(c) Solve 3(22-5) = 4z + 11
Show clear algebraic working.
Answer:
z=10
Step-by-step explanation:
We have to find the value of z.
(3×22)-(3×5)= 66-15= 51
Now,
51=4z+11
4z=51-11
z=40/4
z=10
Hope this helps you :)
There are 9 flash cards with numbers from 20 to 28 written on them. Laura drew the card with 22 on it. She is about to draw another card. What is the probability that the sum of the numbers on these two cards will be a multiple of 5?
Answer:
1 /4
Step-by-step explanation:
Multiples of 5 = (5, 10, 15, 20, 25, 30, 35, 40, 45)
Numbers on card : (20,21,22,23,24,25,26,27,28)
Number on first card = 22
To have a sum which is a multiple of 5 ; number on second card must be either :
23 or 28
22 + 23 = 45
22 + 28 = 50
Since only 2 of the cards will. Result in a sum which is a multiple of 5
Required outcome = 2
Total possible outcomes = (9 - 1) = 8
Probability = required outcome / Total possible outcomes
= 2 / 8
= 1 /4
3 1/4 x 6 2/3 simplified (worked out)
Answer:
65/3 = 21 2/3 = 21.666666667
21.66 = 21.661.
21.661 = (21.66 × 100)(1 × 100) = 2166100.
(2166÷2)(100÷2) = 108350 when reduced to the simplest form.
The is 21 2/3

A police officer gets paid $50 per hour. If she works a holiday, she gets paid time and a half. How much would the officer earn if she worked 7 hours on Christmas day (a holiday)?
a.) $500.00
b.) $525.00
c.) $350.00
Answer:
the correct answer is b $525.00
Step-by-step explanation:
half of her earnings is 25 dollars if she makes time and a half it would be 50 + 25 = $75/hr of overtime (overtime wage)
if she works 7 hours of overtime then... (hours she work) x (overtime wage)
7 x 75 = 525
so her pay would be $525.00
the correct answer would be B

Explanation :
First, you need to convert the mixed numbers into improper fractions. Then, you make sure the denominators are the same. (For example, in the first problem, you have to change the 3/4 to 6/8 to match the 17/8.) Then, you subtract the two fractions, and then turn the resulting improper fraction to a mixed number!

(write a system of equations)
The law of reflection states that when a ray of light reflects off a surface, the
angle of incidence is equal to the angle of reflection.
Ramesh places
a mirror on level
ground to
determine the height of a pole (with traffic light fired on it). He stands at a
certain distance so that he can see the top of the pole reflected from the mirror.
Ramesh’s eye level is 1.5 m above the ground. The distance of Ramesh and the
pole from the mirror are 1.8 m and 6 m respectively.
On the basis of the above information, answer any four of the following
questions:
(i) Which criterion of similarity is applicable to similar triangles?
(a) SSA
(b) ASA
(c) SSS
(d) AA
(ii) What is the height of the pole?
(a) 6 metres
(b) 8 metres
(c) 5 metres
(d) 4 metres
(iii) If angle of incidence is i , which of the following is correct relation?
(a) tan i=5/6
(b) tan i= 6/5
(c) tan i= 3/5
(d) tan i= 5/3
(iv) Now Ramesh move behind such that distance between pole and Ramesh is
13 meters. He places mirror between him and pole to see the reflection of light
in right position. What is the distance between mirror and Ramesh ?
(a) 7 metres
(b) 3 metres
(c) 5 metres
(d) 4 metres
(v) What is the distance between mirror and pole?
(a) 9 metres
(b) 8 metres
(c) 12 metres
(d) 10 metres
