3) Jerry has $400 saved in his bank account and spends $15 a week.

Mathematics
1 answer:
borishaifa [10]3 years ago
6 0

Answer:

No

Step-by-step explanation:

Jerry - 15 x 7 = 105

400 - 105 = 295

Jerry will have 295 in his account

Jack- 5 x 7 = 35

230 + 35 = 265

Jack will have 265 in his account

So no they will not have the same amount in both of their banks

A withdrawal from an account means taking money out of your account. That means whatever money you have in there becomes a smaller amount because you're subtracting money from the account.

So, to work out how much money Jan withdrew as a negative sum, you just have to look at how much she took out:

-25 - 45 - 75 = -$145

This means Jan took out $145 from her account, and we write it with a negative sign because it's money that's going to be taken away from whatever's in there.

The same thing applies to Julie:

-35 - 55 - 65 = -$155

Julie took out $155 from her account, so her withdrawals were -$155.

Therefore, your final answer for 24a. is -$145 and your answer for 24b. is -$155.

Solve the differential equation.<br> question is pictured with answer choices
Nimfa-mama [501]

Integrate both sides with respect to <em>t</em> :

∫ d<em>y</em>/d<em>t</em> d<em>t</em> = ∫ -12<em>t</em> ² d<em>t</em>

<em>y(t)</em> = -4<em>t</em> ³ + <em>C</em>

Use the initial condition to solve for <em>C</em> :

5 = -4•0³+ <em>C</em>

<em>C</em> = 5

So

<em>y(t)</em> = -4<em>t</em> ³ + 5

and the answer is D.

Alternatively, you can directly apply the fundamental theorem of calculus:

\dfrac{\mathrm dy}{\mathrm dt}=-12t^2\implies y(t)=y(0)+\displaystyle\int_0^t -12u^2\,\mathrm du

\implies y(t)=5-4u^3\bigg|_0^t

\implies y(t)=5-4t^3

−3/8 ÷ 1/2= the numbers are fractions
marishachu [46]

\text {Hi! To solve this problem you must...}

\text {Do Keep Change Flip (KCF):}

\text {Keep: -3/8}

\text {Change: /  into *}

\text {Flip: 1/2 into 2/1}

\text {Your new problem should be -3/8*2/1}

\text {The Final Step is to Multiply:}

\text {Note: When Multiplying Fractions you multiply Numerator by Numerator}

\text {and Denominator by Denominator}

\text {-3/8*2/1=}

\fbox {-6/8}

\text {Best of Luck!}

What is the answer to <br> 6+0.10x=0.15x+8
asambeis [7]

Let's solve this problem step-by-step.

6+0.1x=0.15x+8

Step 1: Simplify both sides of the equation.

0.1x+6=0.15x+8

Step 2: Subtract 0.15x from both sides.

0.1x+6−0.15x=0.15x+8−0.15x

−0.05x+6=8

Step 3: Subtract 6 from both sides.

−0.05x+6−6=8−6

−0.05x=2

Step 4: Divide both sides by -0.05.

-0.05x/-0.05=2/-0.05

So, the answer for this problem is x=-40
