The first blank should be -5. The second should be -10. The third one should 10, if it’s talking about the opposite of -10.
Answer:
1. 0.5 = 5/10 ÷ 5 = 1/2
2. 0.7 = 7/10
3. 0.33 = 33/100 ÷ 33 = 1/3
4. 0.875 = (875/1000) ÷ 125 = 7/8
3x-5y=4------eq1
4x+3y=15-------------eq2
multiply 3 to first eq and 5 to second eq.
9x-15y=12
20x+15y=75
subtract both eqs
29x=87 x=3 so put x in eq 1
3(3)-5y=4
5y=5
y=1
