Answer:
m<A = 39
Step-by-step explanation:
1. Approach
To solve this problem, one first has to find the value of "x", then one will substitute "x" back into the equation given for the value of m<A, to solve for m<A. In order to solve this problem, one has to know that the sum of angle measures in a triangle will always equal 180.
2. Solving for "x"
The sum of angle measure in a triangle will always equal 180 degrees, hence one can set up an equation,
m<A + m<B + m<C = 180
Substitute,
(10x - 1) + (18x + 2) + (15x + 7) = 180
Simplify,
43x + 8 = 180
Inverse operations,
43x + 8 = 180
-8 -8
43x = 172
/43 /43
x = 4
3. Solve for m<A
Now all one has to do is substitute the value of "x" back in to solve for m<A
10x - 1
x = 4
10(4) - 1
40 - 1
39

so 0.375 x 24 = 9 make me brainlist pls
Answer:
The answer is 9
Step-by-step explanation:
First, you wanna get rid of the fraction 3/8 so divide 3/8 or 3 ➗ 8 which will give you 0.375. Then multiply 0.375 to 24 to get your product.
Problem:3/8 x 24=?
Step 1:Turn fraction into a decimal
3 divided by 8 =0.375
Step 2:Multiply 0.375 to 24
0.375 x 24= 9
Answer:3/8 x 24=9

Answer:
x = [tex]-\frac{11}{5}, 3[/tex]
y = [tex]-\frac{8}{5},1[/tex]
Step-by-step explanation:
3xy - y² = 8 -------(1)
x - 2y = 1 ------(2)
From equation (2),
x = 2y + 1
By substituting the value of x in equation (1),
3y(2y + 1) - y² = 8
6y² + 3y - y² = 8
5y² + 3y - 8 = 0
5y² + 8y - 5y - 8 = 0
y(5y + 8) - 1(5y + 8) = 0
(y - 1)(5y + 8) = 0
y = [tex]-\frac{8}{5},1[/tex]
From equation (2),
x = 2y + 1
For y = [tex]-\frac{8}{5}[/tex],
x = [tex]-2(\frac{8}{5})+1[/tex]
x = [tex]-\frac{11}{5}[/tex]
For y = 1,
x = 2(1) + 1
x = 3
Therefore, x = [tex]-\frac{11}{5}, 3[/tex]
y = [tex]-\frac{8}{5},1[/tex]
-2(3x+9)=-54
AND 2(3x+4) -3x=35
SHOW WORK PLEASE
Answers
Answer:
1. x=6
2. x=9
Step-by-step explanation:
1.
[tex]-2(3x+9)=-54\\-6x-18=-54\\+18 +18\\-6x=-36\\\frac{-6x}{-6} = \frac{-36}{-6}\\x=6[/tex]
2.
[tex]2(3x+4)-3x=35\\6x+8-3x=35\\3x+8=35\\-8 -8\\3x=27\\\frac{3x}{3} =\frac{27}{3} \\x=9[/tex]
Written Explanation:
1.
-2x(3x+9)=-54
-6x-`8=54 (Distributive property)
Add 18 to both sides
-6x=-36
Divide both sides by -6 (negative divided by a negative equals a positive)
x=6
2.
2(3x+4)-3x=35
6x+8-3x=35 (distributive property)
3x+8=35 (combine Iike terms and then subtract them 6x-3x=3x)
Subtract 8 from both sides
3x=27
Divide both sides by 3
x=9
