2h-3j=-11
2h+j = 1
what the answer?☺️
Answer:
h = -1, j = 3
Step-by-step explanation:
Let's subtract the first equation from the second one:
(2h + j) - (2h - 3j) = 1 - (-11)
2h + j - 2h + 3j = 1 + 11
4j = 12
j = 12 : 4
j = 3
Then let's solve the second equation as we know j:
2h + 3 = 1
2h = -2
h = -2 : 2
h = -1
PQ = 7 and QR = 5 find PR
Answer:
12
Step-by-step explanation:
Both line segments share Q, which is the midpoint:
PQ + QR = PR
Plug in the corresponding numbers to the corresponding variables:
PQ + QR = PR
PR = 7 + 5
PR = 12
12 is your answer.

help with #7 please :) i’ll mark you brainily
Answer:
x = 11
Step-by-step explanation:
The student didn't divide two on both sides in the step 1. This the mistake that the student made.
The correct solution
2√( 3x + 3 ) = 12
Divide 2 on both sides,
2√( 3x + 3 ) / 2 = 12 / 2
√( 3x + 3 ) = 6
Square on both sides,
[ √( 3x + 3 ) ]² = 6²
3x + 3 = 36
3x = 36 - 3
3x = 33
x = 33 / 3
x = 11
Answer:
x=11

help - does anyone know how to calculate the gradient of this?
Answer:
To calculate the gradient of a straight line we choose two points on the line itself. From these two points we calculate: The difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates). If the answer is a positive value then the line is uphill in direction.

What is x squared = 100
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
[tex] {x}^{2} = 100[/tex]
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Answer:
your equation is this... x2 - 100
since you have no x term to the first power you can write 0x... like this
x2 + 0x - 100
Now, what numbers will add to 0 and multiply to -100
The numbers 10 and -10 will
10 + -10 = 0
10 * -10 = -100
therefore
(x - 10)(x + 10) is the way you factor it

Opposite angles in a parallelogram are congruent. Adjacent angles are supplementary.
x = z = 180° -82° = 98°
y = 82°
Answer:
82°+nx360°
82°+1×360°

Answer:
64%
Step-by-step explanation:
Step 1: Divide 16 by 25
-> [tex]\frac{16}{25}[/tex] -> [tex]0.64[/tex]Step 2: Multiply quotient by 100.
[tex]0.64 * 100[/tex] [tex]6.4 * 10[/tex] [tex]64[/tex] 64%Therefore, 16/25 as a percentage is 64%.
Answer:
Well you can make a proportion
Percentage means ”Out of a hundred”
So you can make a proportion with any fraction Equal to x/100 since
X is the unknown perctange.
in this case it’s 16/25
16/25 = x/100
So cross multiply To solve for X
1600= 25x
x= 64
So 64 Percent
In this case you can use benchmarks. If you do it more or long enough, you’d memorize them.
In this case 25 is a bench mark of 1/4 or 25. 25 goes into 100 4 times so you can multiply 16 by 4 to get your percentage since if you do multiply 4, you have to do it to both the numerator and the Denominator.
so 16/25
16*4= 64
25*4=100
64/100 or 64 percent.
Common benchmarks for percentages
5, 10, 20, 25, 50
5 is always multiply by 20
10 is always multiply by 10
20 is always multiplied by 5
25 is always multiplied by 4
50 is always multiplied by 2
