Answer:
2x-12+5=3x-3
1. subtract 3x-2x
-12+5=x-3
2.-12 add to 5
-7=x-3
3. add three to seven
-4=x
Step-by-step explanation:
Find the total amount in grams.
1 kg = 1000 g
1.4 * 1000 = 1400
So she bought a total of 1400 grams.
Add up the grams she used:
400 + 250 = 650
Subtract it from the total:
1400 - 650 = 750
So 750 grams of sequence were left.
Answer:
C
Step-by-step explanation:
Notice that there is a little triangle formed by the lines on the right side of the diagram.
Let's find the angle measures of the triangle. One of them has a supplementary angle of 96 degrees, which means that the actual interior angle is 180 - 96 = 84 degrees.
Another angle has a supplementary angle of 137, which means that the actual interior angle of the triangle is 180 - 137 = 43 degrees.
Finally, we have the expression 2x - 23, which is an exterior angle. By definition, this exterior angle is equal to the sum of the interior angles of the triangle that do not include its supplementary angle. In other words:
2x - 23 = 84 + 43
Now we just solve for x:
2x - 23 = 84 + 43 = 127
2x = 127 + 23 = 150
x = 150/2 = 75 degrees
The answer is 75 degrees, or C.
