Step-by-step explanation:
Answer:
You can make 10 tortillas with one and a half kilograms of ground meat
Step-by-step explanation:
one and a half kilograms to grams
1.5kg x 1000 = 1500g
150 grams prepared to make 1 hamburger
than, 150 x h = 1500
h = 1500 / 150
h = 10
Answer:
I do not know if that x is a multiply sign or a variable so I'm going to answer both
If the x is a multiplication sign then the answer is -20 = -9
If the x is a variable then the answer is x = -2
Step-by-step explanation:
1/2(5 * -8) = -9
(1 * 5 * -8)/2 = -9
(5 * -8)/2 = -9
-40/2 = -9
-20 = -9
-20 ≠ -9
1/2(5x - 8) = -9
1(5x -8)/2 = -9
(5x - 8)/2 = -9
2((5x - 8)/2) = -9 * 2
2(5x - 8)/2 = -9 * 2
5x - 8 = -9 * 2
5x - 8 = -18
+8 +8
------------------
5x = -10
x = -10/5
x = -2
Hi! You don't actually need to graph this nor find the intersection in order to know the answer. Through the process of elimination we can rule out incorrect answers.
Firstly, we express both equations with y on the left hand side since all choices are in that form:


Knowing these, we can immediately rule out options a, c, and d since they have the wrong equations. This will leave us with option b.
You can verify if the point of intersection provided in option b is true by plugging in the values of x and y to both equations (you will find that it is indeed true).
ANSWER: b. <span>picture of coordinate plane with line y equals negative 2x minus 1 and line y equals negative 3 halves x minus 3. They intersect at 4, negative 9.</span>
