Answer:
64 degree and 116 degree
Step-by-step explanation:
4y-44+3y+35=180(Linear pair)
7y=189
y=27
4(27)-44=64
3(27)+35=116
The domain equals all of the x values which are represented on the left in a mapping diagram.
Order the values in order from L to G and put them within braces.
Final answer: x= {3, 6, 8}
Answer:
x + y = 24
16x + 20y = 434
x = 11.5
y = 12.5
Step-by-step explanation:
Part A:
x + y = 24
16x + 20y = 434
Part B:
simplify the second equation to find a "kind of answer" to a variable,
so we could simplify it to either y = 21.7 - 0.8x or x = 27.125 - 1.25y
in this case we will use y = 21.7 - 0.8x
substitute your new value of y into the first equation:
x + (21.7 - 0.8x) = 24
now, we can solve this to find the actual value of x: x = 11.5
so plug in your real x value to the simplified second equation (y = 21.7 - 0.8x)
you get y = 12.5
this tells you how many hours the machine spent on making each type of item
Step-by-step explanation:
2. 10x - 3 + 2x - 5 and 4(3x - 2)
10x - 3 + 2x - 5
Upon simplifying;
10x + 2x - 3 - 5
12x - 8
4(3x - 2)
12x - 8
Both expressions are equivalent - Yes!
3. 3y + 3 and 9(y + 1/3)
9(y + 1/3)
upon simplifying;
9y + 9 (1/3)
9y + 3
3y + 3
Both expressions are not equivalent - No!
4. 6(3x + 1) and 9x + 6 + 9x
6(3x + 1)
upon simplifying;
6(3x) + 6 (1)
18x + 6
9x + 6 + 9x
Upon simplifying;
9x + 9x + 6
18x + 6
Both expressions are equivalent - Yes!
