-(x-3)=-7 I need help with this equation
Answer:
x = 10
Step-by-step explanation:
Given
- (x - 3) = - 7 ( divide both sides by - 1 )
x - 3 = 7 ( add 3 to both sides )
x = 10
x = -1+y
2x - y = 0
All of this is one question it’s simultaneous equations. Can someone please help
Answer:
y = 2
Step-by-step explanation:
x= -1+y
2x-y=0
2(-1+y)-y=0
-2+2y-y=0
-2+y=0
-2+2+y=0+2
y=2
hope it's helpful ❤❤❤❤
THANK YOU.

Answer:
[tex]2( - 1 + y) - y = 0 \\ - 2 + 2y -y = 0 \\ y = 0 + 2 \\ y = 2 \\ x = - 2[/tex]

a leaf blower runs on a mixture of gas and oil. the ratio or ounces of gas to ounces of oil is 40 to 1. how many ounces of gas does the leaf blower need for 2 ounces or oil?
Answer: 80 ounces
Step-by-step explanation:
40 : 1 = x : 2 where x = ounces of gas.
To get from 1 to 2, we multiplied by 2. So, we must also multiply 40 by 2 = 80.
Answer: The answer is 80 ounces

Is algebra.
Answer:
3
Step-by-step explanation:
To find the average rate of change, we can use the formula: (y2-y1) / (x2-x1).
Let (15, 45) be (x1, y1) and (29, 87) be (x2, y2).
So we have: (87-45) / (29-15)
This can be simplified to: 42/14, or 3.

write n^5 x n^2 without exponents
The value without Exponent are n x n x n x n x n x n x n.
What are Exponents and Powers?Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion.
For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as [tex]3^4[/tex], where 4 is the exponent and 3 is the base.
Given:
[tex]n^5[/tex] x n²
Using the Property of Exponents and power
[tex]a^m[/tex] x [tex]a^n = a^{m+n[/tex]
So, [tex]n^5[/tex] x n²
= [tex]n^{5+2}[/tex]
= [tex]n^7[/tex]
= n x n x n x n x n x n x n
Hence, the exponents is n x n x n x n x n x n x n.

1/6 dividend by 3 =
Answer:
1. 1/18
2.1/18
Step-by-step explanation:
In order to multiply fractions, you just multiply it straight out. Numerator to numerator, denominator to denominator.
1*1=1
6*3=18
So, the answer is 1/18.
To divide fractions, you flip the second number. If the number is 3, you flip the 3 to the denominator to make 1/3. Then, you multiply using the rule above.

Answer:
4.0 atm
Step-by-step explanation:
it looks to be a proportional ratio so for every meter pressure increases by .1 atm so if you add .8 to 3.2 you get 4 atm
find the distance between the two given points. O(-3,-2) and P(-3,4)
Answer:
[tex]\boxed {\boxed {\sf d= 6}}[/tex]
Step-by-step explanation:
Distance can be found using this formula:
[tex]d=\sqrt {(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Where (x₁, y₁) and (x₂, y₂) are the points.
We are given the points O (-3, -2) and P(-3,4). Therefore,
[tex]x_1= -3 \\y_1= -2 \\x_2= -3 \\y_2=4[/tex]
Substitute the values into the formula.
[tex]d=\sqrt {(-3--3)^2+(4--2)^2[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
Solve inside the parentheses first.
(-3--3)= -3+3=0(4--2)= 4+2=6[tex]d= \sqrt {(0)^2+ (6)^2}[/tex]
Solve the exponents.
(0)²= 0*0=0 (6)²= 6*6=36[tex]d=\sqrt {0+36[/tex]
Add.
[tex]d= \sqrt {36[/tex]
Take the square root.
[tex]d=6[/tex]
The distance is 6.

How to calculate 46% of 50
Answer:
the answer is 23
Step-by-step explanation:
100/50=2
46/2=23
Answer:
23
Step-by-step explanation:
50/x=100/46
(50/x)*x=(100/46)*x - we multiply both sides of the equation by x
50=2.17391304348*x - we divide both sides of the equation by (2.17391304348) to get x
50/2.17391304348=x
23=x
x=23
now we have:
46% of 50=23
