Answer:
x = 7 , y= - 6
Step-by-step explanation:
4x = -2 - 5y ___(1)
4x= 10 - 3y ___(2)
so, now by simultaneous equations,
10 - 3y = - 2 - 5y
2y = -12
y = -6
if y = -6
then, 4x= 10 -3(-6)
4x =28
x = 7
The first step is to simplify the absolute value. 0.8 - 3/5 is equal to 0.8 - 0.6 which is 0.2. Now we do order of operations. Since the absolute value of 0.2 is 0.2, we can now do PEMDAS and solve. First is multiplication. 0.2 * 10 is 2. Now we have to do 5 - 3 which gives us our answer of 3, or C.
Answer:
0.75 3/4, 0.30 3/10, 0.05 1/20
Step-by-step explanation:
25x3 is 75 but because its 75 cents its 0.75
and 3/4 means 0.75 (3 divided by 4 is 0.75)
10x3 is 30 but because its 30 cents its 0.30
and 3/10 means 0.30 (3 divided by 10 is 0.30)
1x5 is 5 and because its 5 cents its 0.05
and 1/20 means 0.05 (1 divided by 20 is 0.05)
