Answer:
Numbers are 28 and -15
Step-by-step explanation:
Mark first number X, and second number Y, then:
x-y=43
and
x+y=13
We get system of two equations. Solve it by add both them together:
x-y+x+y=43+13
2x=56
x=28 we get first number
x+y=13
28+y=13
y=13-28
y=-15
It is 6 60 divided by 10 is 6
Answer:
B
Step-by-step explanation:
Ok so lets say D= Dog And C=Cat
D+C = 54
D = 8C
<span>
Now, substitute 8C for D in the first equation to get: </span>
<span>8C + C = 54 </span>
<span>Solving for the cat gives us C = 6 </span>
<span>D = 8 x 6 = 48
</span>Dog Weighs 48 Pounds
