BRAINLIEST NEED ASAP More than 4,000 years ago, people in ancient Babylonia used math to calculate how much land to use for farming and how much of each crop they harvested. They also used math to calculate how much tax to charge people.

Today, we use algebraic tools such as writing and solving equations, systems of equations, inequalities, and systems of inequalities to help us measure and interpret real-world scenarios. What twenty-first century tasks do these tools help us manage?

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

=240

=48
