@jessiehuang_ Evaluate 5(a – 2b) when a = –3 and b = 5. A. 65 B. 35 C. –65 D. –25

@jessiehuang_
-65
5(a - 2b) a = -3, b = 5 substitute your values of a and b into your expression 5(-3 - 2(5)) 5(-3-10) 5(-13) -65
Evaluate –6(x – 2y) when x = –3 and y = –5 A. –42 B. 80 C. –80 D. –16
-42
these are not that hard to do...just sub in your values into the expression and solve mathematically. jessie..be careful just giving answer...you can get booted off for that
Simplify: (–5) • (7) – (6) • (–2) A. –23 B. –35 C. 10 D. 47
oh i'm sorry, i'm multi-tasking with my english homework and open study, i'll try and show explanations from now on @kelliegirl33 but thanks for the heads up :)
Simplify: (–5) • (7) – (6) • (–2) A. –23 B. –35 C. 10 D. 47
no problem...I learned the hard way and got booted for 2 weeks by just giving answers
Simplify: (–5) • (7) – (6) • (–2) A. –23 B. –35 C. 10 D. 47
ok just multiply from left to right; -5*7=-35 -(-6)*(-2)=12 combine: -23
so its A
yes
Simplify: –5(x – 3) + 2(a – 9) A. –5x + 2a + 33 B. –5x + 2a + 4 C. –5x + 2a – 3 D. –5x + 2a – 33
ok so distribute both parenthesis: -5x+15+2a-18 rearrage: -5x+2a+15-18 combine like terms: -5x+2a-3 so c
Simplify: –6(x – 3) – 4(y + 5) + (–5)(7 – 2b) A. –6x –4y – 10b – 3 B. –6x –4y + 10b – 37 C. –6x –4y + 10b + 3 D. –6x –4y + 10b + 33
–6(x – 3) – 4(y + 5) + (–5)(7 – 2b) distribute: -6x+18-4y-20-35+10b rearrange: -6x-4y+10b+18-20-35 combine like terms: -6x-4y+10b-37 b
oh
u got me 100% again omg u should be a mod
close and reopen ok
just make sure to tag.
ok
