Answer:
90/23
Step-by-step explanation:
First, you want to start in the parentheses. 5-6=-1, then multiply it by -2. Since a negative multiplied by a negative is a positive, -2*-1=2. -3^2=-9. 2+8=10. Then -9 times 10= -90. Then, we move on to the bottom. 5--2=7. 4^2=16, and -2(2)=-4. So -5(7) + 16-4=-23. Now, the equation should look like this, -90/-23. Put the negatives together and you get 90/23.
Answer:
3/8
Step-by-step explanation:
slope = rise/run = 3/8
Put 3x + 3y = 45 in slope intercept form
y = 15 - 3/3x
(-3/3x is just going to simplify to -1x though)
Perpendicular form of -1x would be 1x
So your perpendicular slope would be 1
Answer:
Base = 6 inches
Step-by-step explanation:
30 divided by 1/2 equals 60. 60 divided by 10 equals 6.
To check:
A = 1/2bh
30 = 1/2 x 6 x 10
30 = 30 ✅
I take it that the actual total is 538. If it really is 538538 leave me a note.
Let the first number = x
Let the second # = 44x
Let the third # = 100x
Equation
x + 44x + 100x = 538 Add the left side. All terms are part of the total.
145x = 538 Div By 145
x = 538/145
x = 3.71
Check
First number = 3.71
Second # = 44*3.71 = 163.24
Third number = 100*3.71 = 371
Total these 3 numbers 537.95 The very tiny difference is due to rounding.
