Answer:
2.2
Step-by-step explanation:
3.7+(-1.5) to find the distance subtract second number from the first or in this case the absolute value of the second number from the first
Answer: x = -3, y = 2
<u>Step-by-step explanation:</u>
3x + 2y = -5 → 3(3x + 2y = -5) → 9x + 6y = -15
4x - 3y = -18 → 2(4x - 3y = -18) → <u> 8x - 6y </u>= <u>-36 </u>
17x = -51
<u> ÷17 </u> <u>÷17 </u>
x = -3
3x + 2y = -5
3(-3) + 2y = -5
-9 + 2y = -5
<u> +9 </u> <u> +9 </u>
2y = 4
<u> ÷2 </u> <u>÷2 </u>
y = 2
Note that the given (15•3)-20 involves multiplication and subtraction. The mult. must be carried out first. Thus, (15•3)-20 = 45-20, or (3*15)-20. Only answer B is equivalent to (15•3)-20.
Answer:
9y+45
Step-by-step explanation:
just multiply 9 by (y+5) that's what it means when it's right next to the parentheses without a sign in the middle.
