Answer:
Question Number 1: C. -58 meters
Question Number 2: 1.45 lbs
Step-by-step explanation:
<em><u>Question Number 1: </u></em>
40 - 12 = 28 meters below sea level
28 + 30 = 58 meters below sea level . So respectively its negative, so -58 would be your answer .
<em><u>Question Number 2: </u></em>
To figure out how many pounds of carrots are in each cake, divided 7.25 by 5. That equals 1.45. So one cake needs 1.45 pounds of carrots.
Answer:
<h2>The easiest to solve for is x in the first equation</h2>
Step-by-step explanation:
Given the system of equation, x + 4 y = 14. and 3 x + 2 y = 12, to solve for x, we can use the elimination method of solving simultaneous equation. We need to get y first.
x + 4 y = 14............ 1 * 3
3 x + 2 y = 12 ............ 2 * 1
Lets eliminate x first. Multiply equation 1 by 3 and subtract from equation 2.
3x + 12 y = 42.
3 x + 2 y = 12
Taking the diffrence;
12-2y =42 - 12
10y = 30
y = 3
From equation 1, x = 14-4y
x = 14-4(3)
x = 14-12
x = 2
It can be seen that the easiest way to get the value of x is by using the first equation and we are able to do the substitute easily <u>because the variable x has no coefficient in equation 1 compare to equation 2 </u>as such it will be easier to make the substitute for x in the first equation.
Answer: B= A/(C+D)
Step-by-step explanation:
A = B(C+D)
Divide each side by B
A/B= C+D
Reciprocate both sides
B/A = 1/(C+D)
Now multiply each side by A
B = A/(C+D)
Jamal's age is 5 because Tim is 3 years younger which is 2 and add those two together and you get 7 and Wilma is twice his age so 10 and add the others
Ok the question dosent make sence you said hundreds place but it only goes up to tenths so if we were going by tenths place the answer would be 70
i hope i helped
