Answer:

The correct option is 1.

Step-by-step explanation:

The given expression is

$3.5\times 2+9(7.1+0.5)+4$

To solve these type of expressions we have a rule that is known as BODMAS.

BODMAS = brackets of division, multiplication, addition, subtraction.

It defined the order of calculations. It means first we have solve the brackets, then division, then multiplication, after that addition and last subtraction.

So according to BODMAS, Claudio should simplify the bracket first.

The bracket of given expression is (7.1+0.5).

The simplification of given expression is shown below.

$3.5\times 2+9(7.6)+4$ (Brakets)

$7+68.4+4$ (Multiplication)

$79.4$ (Addition)

Therefore he will solve (7.1+0.5) first. So, option 1 is correct.

1 7/8 divided by 3/4 can someone please help me

sesenic [268]

1. Change 1 7/8 to an improper fraction, which gives you 15/8.

2. Use KFC to divide fractions. KEEP the first term, FLIP the second and CHANGE to multiplication.

3. 15/8 x 4/3 = 60/24 = 2 1/2

Please help me with this math problem!! :) Will give BRAINLIEST!! :)

The rate of change will be positive and a point in the graph will be (1,250);
the function then would be y = 250x;
after 1 year she will owe USD 5,250;
she will have to make 33 payments.

How to form equation using slope and one point?
y - y1 = m(x - x1) is the equation of a straight line's point slope form, where m is the line's slope and (x1, y1) is the point through which the provided line passes.

Using slope-point equation, the equation for the payment can be taken as:
y-250 = [(500-250)/(2-1)]*(x-1)
y - 250 = 250*(x-1)
y = 250 + 250x - 250 = 250x;
Putting x = 12, for a year the amount paid is USD 3,000.
Amount she owes = USD (8250-3000) = USD 5,250;
Total amount to be paid (in USD) = 8250
Amount paid per month (in USD) = 250
Thus, number of payments required = 8250/250 = 33

Thus, the rate of change will be positive and a point in the graph will be (1,250); the function then would be y = 250x; after 1 year she will owe USD 5,250; she will have to make 33 payments.

X^2+4=square root 13

beks73 [17]

Answer:

$\large\boxed{x=-\sqrt{\sqrt{13}-4}}\ \vee\ x=\sqrt{\sqrt{13}-4}}$

Step-by-step explanation:

$x^2+4=\sqrt{13}\qquad\text{subtract 4 from both sides}\\\\x^2+4-4=\sqrt{13}-4\\\\x^2=\sqrt{13}-4\Rightarrow x=-\sqrt{\sqrt{13}-4}}\ \vee\ x=\sqrt{\sqrt{13}-4}$
