Answer:
(75x2)+(6-3)
These equations are in parentesis so they happen first.
75x2=150. If we take 70 and multiply it by 2 we get 140. If we multiply 5 by 2 we get 10. So 140+10=150.
6-3 is next. That is common knowledge and we know its 3.
No we add 150+3=153 to get our answer.
Parenthesis first
Exponets after parenthesis
Multiplying going left to right
Divinding left to right
Adding left to right
Subtracting left to right

I hope this helped and if so plz give brainliest.
Answer:
x= -13
Step-by-step explanation:
-4(2)=-8
-8-5=-13
x=-13
In this item, we are given with a system of linear equation as written below.
y = 0.5x + 3.5
y = -2x/3 + 1/3
To determine the values of x and y, we use the substitution method. We substitute the expression for y from the first equation to that of the second equation so that the equation becomes.
0.5x + 3.5 = -2x/3 + 1/3
Multiply the equation by 6.
3x + 21 = -4x + 2
Transpose all the terms with variables to one side and the constants to the other.
(3x + 4x) = 2 - 21
7x = -19
Divide the equation by 7,
x = -19/7
The value of y,
y = (0.5)(-19/7) + 3.5 = 15/7
<em>ANSWER:</em>
<em> x = -19/7</em>
<em> y = 15/7</em>
Answer:
CD = (3/2)√2
Step-by-step explanation:
All the triangles are similar isosceles right triangles, so the hypotenuse in each case is √(1²+1²) = √2 times the length of the corresponding legs. BC is the hypotenuse of ΔBCD, so leg CD is that length divided by √2.
CD = BC/√2 = 3/√2
CD = (3/2)√2
It’s 40:15 because 8*5=40 and 3*5=15
