Answer:

m∠ABD = 88°, m∠CBD = 23°

Step-by-step explanation:

m∠ABD + m∠CBD = m∠ABC = 111°

(-10x + 58) + (6x + 41) = 111

-4x + 99 = 111

-4x = 12

x = -3

m∠ ABD = -10(-3) + 58 = 88°

m∠CBD = 6(-3) + 41 = 23°

Answer:

Step-by-step explanation:

X= -3

Abd = 88 degrees

Cbd = 23 degrees

Set the equation this way and solve:

-10x + 58 + 6x + 41 = 111

-4x + 99 = 111

-4x = 12

X = -3

kicyunya [14]

Answer:

$40 million

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Current value = 125%

which means that current value is 25% more than its initial value.

Let Initial Value = X

So, Increase in investment value = 25% × X = 0.25X

Given, increase value = $10million

So, 0.25X = $10 million

= X = $10million

= X = $10million ÷ 0.25

= X = $40 million

Hence the initial value of investment is $40million.

Mario says that the expression 4+3n² has four terms: 4, 3, n, and 2. Is he correct? explain.

stich3 [128]

Mario says that the expression $4+3n^2$ has four terms: 4, 3, n, and 2. Mario is incorrect

<em><u>Solution:</u></em>

Given that the expression is:

$4+3n^2$

Given that, Mario says that the above expression has four terms

But Mraio is incorrect

Because the given expression has two terms only

4 is one of the term

$3n^2$ is another term

So there are totally 2 terms only

A term can be a signed number, a variable, or a constant multiplied by a variable or variables

Here 3 is a constant multiplied by $n^2$

So, $3n^2$ is one term

Each term in an algebraic expression is separated by a + sign or - sign

Thus there are two terms in mario expression
